VFI underground distribution switchgear

Electrical Apparatus

GeneralEaton’s Cooper Power Systems VFI underground distribution switchgear provides superior overcurrent protection through the use of proven, reliable vacuum fault interrupters from Eaton’s Cooper Power Systems. The resettable vacuum fault interrupter allows immediate service restoration, eliminating the added expense and downtime associated with stocking and replacing fuses.

Deadfront construction provides a higher level of safety for operating personnel. With the addition of visible-break switches, circuits can be isolated and grounded without disconnecting or moving terminations.

A sealed insulation system offers the further advantage of low-maintenance, and permits construction of a compact, low-profile unit that is less obtrusive than a comparable air-insulated design. Insulation options include the environmentally-preferred high-fire-point E200™ fluid and Envirotemp™ FR3™ fluid, as well as mineral oil and Sulfur Hexafluoride (SF6) gas.

VFI switchgear is used for commercial/industrial and utility applications, and can be easily coordinated in the field without a PC, using field-selectable settings to meet distribution system protection requirements. Ratings of VFI switchgear are shown in Table 1.

Features and detailed descriptionVFI switchgear

Eaton’s Cooper Power Systems VFI underground distribution switchgear provides a simple, economical approach to protective requirements for 5, 15, 25, and 35 kV underground systems.

The deadfront construction of VFI switchgear improves safety for utility personnel and the general public. Inside, all terminations are covered with insulating rubber that is grounded. All internal parts are completely sealed in a steel tank to reduce maintenance and elimi-nate the problems of moisture, dirt, and wildlife.

This fluid-insulated, sealed design offers an added advantage: an unobtrusive, low-profile appearance.

VFI switchgear is versatile in its application. It is suited for commercial/industrial and utility requirements.

Single-sided compact style VFI switchgear units are ideal for areas where access is limited; such as next to a transformer, behind a building, against a wall, or in a vault. The VFI vault-style unit is suitable for indoor applications including commercial and industrial electrical equipment rooms. 5- and 6-way units are ideal for large retail complexes and campuses (military, university, industrial park) with multiple loads.

For sustained reliability, Eaton’s Cooper Power Systems VFI switchgear has 30 years of excellent field performance. The VFI switchgear’s interrupting duty cycle is unmatched in the industry, providing a full 232 interruptions per IEEE Std C37.60™-2003 standard (see Table 2).

Tri-Phase control

The Tri-Phase electronic control provides a flexible solution for time-current-curve coordination. The Tri-Phase control offers over 100 minimum trip settings and an assortment of time-current curves. With standard instantaneous trip and optional ground trip and minimum response characteristics, the Tri-Phase control will satisfy system protection and coordination needs. A wide selection of TCCs and minimum trip settings make it easily adaptable to distribution systems.

Edison™ Idea™ relays

Edison™ Idea™ relays allow enhanced functionality in protection and communication.

The IDEA Workbench™ embedded within the ProView™ software allow unsurpassed flexibility in customizing the relay protection and control functions through downloadable Custom Software Modules.

Depending on the relay selected, Edison Idea relays can provide protective functions such as overcurrent with or without ground detection, over/under voltages, reverse power, and negative sequence to name a few.

Advanced metering and analytics are also available which are critical to providing Distribution Automation capability.

Single- or three-phase tripping

Most commercial loads consist of large three-phase transformers. Many transformers are protected with single-phase fuses. Typically, only one of the fuses will open during an overcurrent condition. This “single-phases” three-phase commercial loads, and may cause damage to three-phase motors and other equipment. VFI switchgear solves this problem by providing three-phase ganged tripping. An overcurrent on any phase automatically opens all three phases simultaneously.

VFI switchgear can also be specified with single-phase trip, to provide individual phase protection for single-phase residential applications.

VFI switchgear can also serve as a vacuum loadbreak switch. Tap switching has traditionally been accomplished by pulling loadbreak elbows. With VFI switchgear, the tap can be switched with a simple push-pull of the operating handle.

Vacuum loadbreak switch

Source switching is accomplished by three-phase, vacuum loadbreak switches. The ratings for the vacuum switches are in Table 1.

Visible-break switch

Visible-break switches are available in two versions—a two-position switch (closed/open) and a three-position switch, (closed/open/ground). Visible-break is accomplished by a separate switch operated from the side of the unit—away from the high voltage compartment. This switch is mechanically interlocked such that the vacuum load-break switch or the vacuum fault interrupter mechanism first interrupts the current and then the visible-break switch may be operated. The visible-break switch is rated 600 A continuous current and has a making current rating up to 16 kA (sym). The ground position allows the cables to be grounded without disconnecting or moving the terminations. The switch contact positions are visible via a large viewing window above the associated bushings. Only VFI switchgear with liquid dielectric may be equipped with a visible-break feature.

Types of insulation

Eaton’s Cooper Power Systems offers underground distribution switchgear with the widest availability of dielectric media in the industry. Fire-resistant E200 fluid and Envirotemp™ FR3™ fluid, as well as commonly used mineral oil and SF6 gas, are offered as insulation media for VFI switchgear.

E200 fluid

E200 fluid is fire-resistant biodegradable, polyol ester-based, non-toxic low viscosity fluid with excellent dielectric, thermal and physical properties. The low viscosity characteristic allows it to be used in VFI switchgear down to -30 °C. Its fire point is greater than 300 °C (572 °F), a requirement for less flammable fluids.

The performance of the switchgear equipment containing E200 fluid is further enhanced by the fluid’s other important properties:• Excellent thermal properties• High dielectric strength• Oxidation stability• Clear bright appearance

Envirotemp™ FR3™ fluid

Envirotemp™ FR3™ fluid is formulated from edible vegetable oils and food grade performance enhancing additives. It does not contain any petroleum, halogens, silicones, or any other questionable material. It quickly and thoroughly biodegrades in both soil and aquatic environments. The fluid tested non-toxic in aquatic toxicity tests.

Mineral oil

Mineral oil is a petroleum-based, time-proven insulation and has reliable electrical insulating properties.

SF6

SF6 is non-flammable, odorless, colorless gas that requires a gas-tight design and gas monitoring and handling systems.

Low Profile sealed construction

VFI switchgear features a low-profile cabinet design, with sealed tank construction. This means that VFI switchgear can be used in locations where air-insulated switchgear cannot, such as flood areas or high-contaminant industrial sites. It is resistant to attacks from dust, ice, vegetation, and wildlife.

Stainless steel

VFI switchgear may be specified in 100% stainless steel construction for the ultimate in corrosion protection. With VFI switchgear from Eaton’s Cooper Power Systems, the entire unit is designed in stainless steel, including the tank and cable compartments. All details and accessories are stainless steel as well. This construction meets the requirements of IEEE Std C57.12.29™-2005 standard, Standard for Pad-Mounted Equipment–Enclosure Integrity for Coastal Environments.

Trip-free operation

The vacuum fault interrupter mechanism can be quickly and easily reset manually by pulling the handle to the “reset” position and then moving it to the closed position. However, if a fault is present when the vacuum fault interrupter mechanism is closed, the trip-free feature will prevent the mechanism from being held in the closed position and it will clear the circuit fault.

UL® Listed and Labeled

VFI switchgear and a number of its features can be UL® listed and labeled to meet customer requirements as necessary. These features are available for the family of VFI switchgear products as follows:• 15 kV and 25 kV voltage ratings• 600 A continuous current rating• 12.5 kA symmetrical interrupting rating• Fluid Dielectrics (mineral oil, E200 and Envirotemp™ FR3™ fluids)• Visible-break switch (two- and three-position)• Mild and stainless steel construction• Tri-phase and TPG control

Low maintenance

Both load and fault interruption take place within the sealed vacuum fault interrupter with no arcing by-products to contaminate the insulating medium. Advanced technology vacuum fault interrupters are reliable, have long life and require no maintenance. Eaton’s Cooper Power Systems patented design reduces the arc energy—resulting in far less contact erosion and the longest life of any vacuum fault interrupter in the industry. Since there are no expulsion fuses or switching by-products to contaminate the insulation medium, maintenance intervals are greatly increased.

Edison™ Idea™ relay and Tri-Phase control

Eaton’s Cooper Power Systems Edison™ Idea™ relay and Tri-Phase control makes use of internally mounted 1000:1 current transformers (CT), one on each phase, to monitor line current. If the current in any phase exceeds the minimum trip level setting, the control begins a user selectable time-current-curve (TCC) delay sequence.

At the completion of the programmed TCC delay, a signal is issued to trip the vacuum fault interrupter mechanism.

CT circuits

The Tri-Phase control is self-powered by the line current. It requires no external voltage supply or battery backup. Since the Tri-Phase control is powered by the sensing CT circuits, it is not affected by system voltage conditions.

Edison Idea relays require a 120 Vac power source to power their internal battery source. The standard battery provided is an 13 Ah. 18 Ah batteries are an option.

Tri-Phase control settings

The minimum-trip setting for each phase is selectable. This permits convenient field configuration of the Tri-Phase control, to meet spe-cific application requirements.

The control features an assortment of field replaceable TCC mod-ules, each provides a fixed time-current-curve characteristic. The variety of modules available provides coordination flexibility between the Tri-Phase control and other protective equipment.

Figure 5. TPG control with SCADA shown.

Figure 6. Tri-Phase control settings.

Tri-Phase Control Settings

Each phase minimum trip = Sum of values in “ON” position plus 20 A.

Example is shown as: øA= 10 + 20 + 80 + 320 + 20 = 450 A øB = 320+20 = 340 A øC = 20 A

Instantaneous Trip = Sum of values in “ON” position plus 1X. Example is shown as: 2X + 8X + 1X = 11X

Each phase will exhibit instantaneous tripping at 11 times its trip setting in this example.

Tri-Phase control normal load

At normal system current, the Tri-Phase control is effectively dormant. Load current is continuously being compared to the selected minimum-trip settings, but the TCC and trip circuits are not activated.

Tri-Phase control overcurrent protection

The TCC circuit is activated when current above the pre-selected minimum trip value is sensed. Once activated, the TCC circuit uses the magnitude of the overcurrent to establish a time delay. At the completion of the delay, the trip circuit pulses the Flux Shift Tripper, which causes it to trip open the vacuum fault interrupter mechanism.

Tri-Phase control coordination flexibility

The E time-current curve has long been an industry standard for underground distribution switchgear fusing. However, when several protective devices are present on the same line, it can become difficult to obtain proper system coordination. The Tri-Phase control, with the EF TCC installed, combines classic switchgear protection with state-of-the-art vacuum fault interrupter technology. The Tri-Phase control eliminates the problems normally associated with fuses, but preserves and extends the familiar E-shaped curve to higher currents.

Coordination and application of the Tri-Phase control is identical to fuse application, but with the benefit of a greatly expanded offering of trip ratings and timing curves. In the following example, the EF TCC provides ideal coordination when protecting single-phase distribution transformer loop schemes. The cable can be protected to its rated load with sufficient margin between the EF and the substation breaker.

Tri-Phase control instantaneous trip

Instantaneous trip, a standard feature of the Tri-Phase control, extends the range of coordination with upstream devices, at higher fault levels. A switch on the control circuit board enables the instantaneous trip feature and programs a multiplier that is applied to the standard minimum trip setting. When current above the predetermined fault level is sensed, the instantaneous trip feature causes the control to bypass the normal TCC delay and trip immediately; thus eliminating any intentional time delay. For faults below this actuation level, the control operates according to its normal settings.

In the example, the EF curve coordinates well with the transformer fusing, although instantaneous trip is required to extend coordination with the upstream T-Link.

Optional Tri-Phase with ground trip control (TPG)

The optional TPG control operates under the same algorithm as the standard Tri-Phase control for phase protection. In addition, the TPG control has a separate zero-sequence circuit and settings for ground protection. Settings for ground trip vary from 10 A to 640 A in 10 A increments, and are field selectable by the user.

In some applications, such as a switchgear tap that feeds both underground and overhead feeders, the TPG control is necessary. As shown below, the F curve achieves coordination with both the phase and ground settings of the upline recloser.

Tri-Phase control accessories

Minimum response time

The minimum response time accessory is used to achieve coordina-tion between in-line protective interrupting devices, located where fault-level currents would normally cause simultaneous tripping.

The accessory inhibits tripping until a predetermined minimum time has elapsed; available minimum response times are adjustable at 0.050, 0.100, 0.145, 0.205, 0.260, 0.335, 0.405, 0.495, or 0.580 sec-onds. Refer to the example below.

Minimum trip multiplier

The minimum trip multiplier accessory allows the user to increase the programmed minimum trip setting, to a predetermined alternate setting, by operating a toggle switch. Typical applications for an alternate minimum trip settings include: preplanned or emergency load transfers, maintenance, or other routine switching conditions where line or feeder load temporarily exceeds the normally anticipated levels.

TPG ground trip control

The TPG control includes phase and ground-fault protection for systems where increased sensitivity is required. If a ground-fault is detected, the control will begin a time-current curve delay sequence. At the completion of the programmed delay, a signal is issued to trip the vacuum fault interrupter mechanism.

Since the ground-fault curves are more sensitive than the phase curves, they can offer a distinct advantage in those special applications where increased sensitivity and speed in overcurrent protection are required. As a result, coordination with upstream devices (i.e., electronic reclosers) can be obtained where TCC coordination is difficult.

TPG SCADA accessory

VFI switchgear, when ordered with the TPG control, may also be supplied with an optional SCADA accessory. The SCADA accessory provides the user with remote functionality, along with Status and Fault indicators, for each TPG-controlled vacuum fault interrupter mechanism. For additional information, refer to Service Bulletin S285-75-1, Tri-Phase, TPG, and TPG with SCADA Electronic Control Installation and Operation Instructions.

Customize with the IDEA Workbench

Edison Idea and IdeaPLUS relays are fully functional relays, ready to use right out of the box. However, there are applications where custom control logic, or custom functions need to be added to the relay. The IDEA Workbench is a revolutionary graphical software programming environment which permits the user to customize the relays.• Add new features or protective functions by means of IDEA

Workbench Custom Modules. These operate in the same fashion as the plug-ins for popular internet browsers. Your investment in the relay is protected as future needs and developments may be addressed through new Custom Modules.

• Create custom control and protection logic using over 400 programming signals and tools, all selectable from drag-off Toolboxes. Logic created suing these tools can then be saved as Custom Modules to be reused or shared with associates.

• Monitor and control practically every aspect of the relay’s operation• Create custom metering and measurement quantities• Create custom sequence of event records• Configure communication protocols to match existing SCADA

system mappings

The IDEA Workbench offers the user the ability to rapidly and accurately create customizations by working the way the engineer thinks, by using logic diagram and flowchart construction methods. No equation-based or command-based logic programming is required.

The IDEA Workbench also addresses some of the more difficult questions associated with custom relay programming, namely:

Clarity: Compared to that offered by equation and command based programming techniques, graphical programming results in customizations whose operation is intuitive.

Testing: ProView provides a Virtual Test Set (VTS), which can be used to test the developed logic with realistic fault signals. During test, the logic diagrams become “live” showing the state of all variables, logic gates, contacts, counters, etc. To avoid any question of how the custom logic interacts with the relay itself, the VTS environment models the entire relay in addition to the custom programming. Unlike other programming environments, the IDEA Workbench does not require the user to have an actual relay or relay test set on hand to verify the proper operation of the programmed logic.

Documentation: Notes regarding how the custom logic operates may be embedded within the IDEA Workbench. This improves the ability of others to quickly understand how the logic is designed to work. Links to external files may also be embedded in the IDEA Workbench, providing fast access to larger documents stored on company’s network servers.

Portability: If the original data files are lost, the entire IDEA Workbench may be uploaded from the relay, complete with logic diagrams, embedded notes and external reference links.

Event records and analysis tools

The iDP-210 relay shares the same event records and analysis tools as all Edison Idea relays. The Edison Idea allows for the display of event records in a variety of formats including waveforms (oscillography), magnitude plots, phasor diagrams, symmetrical component diagrams and more. ProView, the software for the Edison Idea relay, also provides a unique Application Diagram View that provides a one-screen view of everything that is going on in the relay. Many of these event views are also available in On-Line View mode, where it is possible to monitor the status of the relay in real-time, including phasor diagrams, which is ideal for verifying CT phasing during commissioning. The iDP-210 relay also includes distance to fault indication.

Relay Replay™

To evaluate the effect different settings would have on the relay, the Relay Replay™ feature of the Edison Idea software allows the user to make any number of setting changes and replay an existing event using these new settings without the need for an actual relay or expensive test equipment. The operation of every aspect of the relay’s performance, from which elements pick-up, the response time of those elements that do and the operation of any custom programming made via the IDEA Workbench can be observed. This tool provides unprecedented “what-if” analysis capabilities.

Virtual Test Set (VTS)

To evaluate settings against any arbitrary fault, the Edison Idea software permits the user to create a virtual event record through use of the software’s VTS feature. The VTS allows complete control over:• Pre-fault and post-fault voltage and current levels• Selection of phase-ground, phase-phase, phase-phase-ground and

three-phase fault types• Fault duration• Selection of system and fault impedances• Selection of DC time constant• Control over fault dynamics to verify reclosing sequences and

sequence coordination• Control of frequency change, rate of change, and acceleration

during faults• Control over simulated breaker open and close times• Voltage and current parameters derived from a built-in power sys-

tem model or entered manually.

Communications

Both Modbus RTU and DNP 3.0 communication protocols are included with the iDP-210 relay. A Communications Workbench™ provides the user the ability to customize communication maps, add or delete information, add control points, and even create new signals to be brought out through communications. The iDP-210 relay features two RS-232 auto-baud (57600 kbps max) communication ports and one port configurable for RS-485, serial fiber optic, and various Ethernet options (RJ-45, multi-mode fiber, single-mode fiber). Contact your Eaton’s Cooper Power Systems representative for availability of other communication protocols.

Incipient cable splice fault detector (ICSF)

One of the most common causes of buried cable failure is from moisture ingress to buried cable splices. When sufficient water accumulates in the splice, a line-to-ground fault briefly occurs. The fault is cleared as the water is suddenly converted in to steam. Over time, the insulation is damaged and the cable splice eventually fails. The iDP-210 relay contains an algorithm to recognize the unique waveform characteristics of these self-clearing faults. See Figure 12. By counting how often these events occur over a moving time window, the iDP-210 relays are able to give advance notice of pending cable splice failures. This permits cable maintenance to be scheduled rather than addressed on an emergency basis.

Overcurrent protection

The iDP-210 relay offers inverse time, definite time (2 levels) and instantaneous elements for phase, residual and negative sequence overcurrent protection. An additional definite time ground overcurrent element is provided for a separate zero-sequence flux summing CT. This fourth current channel input may also be ordered in a sensitive earth fault version which may be set as low as 0.005 A secondary. Each overcurrent element may be independently selected to be non-directional, forward- or reverse-directional. Inverse time elements may be set for disk-like or instantaneous reset characteristics. Complete fuse-fail detection logic is also included to selectively non-directionalize or disable directional elements during loss of bus potential.

Motor operators

VFI switchgear may be specified with motor operators and an asso-ciated control to allow for local or remote opening and closing of the switches and vacuum fault interrupters via SCADA command.

Motor control is available either via the Edison Idea relays or with a separate DC Motor Controller.

Edison Idea relays can control up to two (2) individual motors on the operating handles. With this option, the motor control is integral to the relay.

The stand alone DC Motor Controller may operate up to six (6) indi-vidual motors on the operating handles. Additional motor controllers can be supplied if more than six (6) motors are required.

ways, 200 A bushing wells on 200 A ways

Example:To specify a VFI unit use the following procedure:

1. Build the descriptor by completing the fields based on the Switchgear requirements:

For example, KPDE-VF9-32 is the descriptor for the following standard unit:• Pad-Mounted, Double-Sided unit

• E200 Fluid insulation

• 15 kV, 600 A deadbreak bushings on source ways, 200 A loadbreak bush-ing wells on tap ways

• Model 9 - Two switched source ways and Two vacuum fault interrupter protected Tap ways

• Mild-Steel construction

• Side-hinged doors

• Tri-phase control for the vacuum fault interrupter tap ways (Tri-Phase control with “EF” TCC curve is the standard control that ships with the VFI unit. If a different control is required, select the appropriate control from Table 10 and the desired TCC curve from Table 11.)

• Unit is of standard Bell Green/Munsell 7GY paint. If custom color is required, refer to Table 12.

2. Identify the options or accessories for inclusion with the standard unit. Refer to Tables 7-21.

3. Submit the descriptor with a list of options and accessories to your Eaton’s Cooper Power Systems representative for a quotation.

GeneralType MOST pad-mounted switchgear from Eaton’s Cooper Power Systems (Figure 1) offers a simple, economical approach to under-ground switching . In addition to the inherent advantages of pad-mounted apparatus for underground switching, the Type MOST modular design provides a wide selection of switching combinations to meet specific requirements without the added cost of custom construction .

Deadfront construction provides a high level of safety for both the operator and the general public, and oil insulation offers the further advantage of low maintenance .

Oil insulation also permits construction of a compact, low-profile unit that is considerably less obtrusive than a comparable air-insulated design .

Type MOST switchgear can be used for both utility and commercial/industrial applications and can be easily fused to meet distribution system requirements . Ratings of Type MOST pad-mounted switchgear are shown in Table 1 .

DescriptionEaton's Cooper Power Systems VACpac™ switchgear may be used to switch load, loop, capacitor, cable charging and magnetizing currents. VACpac switchgear may be installed on distribution systems having voltage ratings lower than nameplate and retain all other ratings. VACpac switchgear has a capacitor switching duty cycle of greater than 7,000 operations. VACpac switchgear vacuum bottle interrupters feature the highest duty cycle of any distribution system, making it ideally suited for automated applications that require a large number of switching operations.

Note:N Elbow type connectors are required for terminating cables to VACpac switchgear. This permits the implementation of local or industry established safety procedures by qualified personnel for testing, visibly isolating and/or grounding high voltage de-energized cables when maintenance of cables or associated equipment is required after a switching operation. In some cases, local conditions may dictate that supplementary equipment be used to perform these procedures.

Eaton's Cooper Power Systems switch technology in VACpac switchgear provides the distribution engineer with the ultimate in modern switchgear design. It features the proven technology of vacuum interrupters supported by more than five decades of successful VACpac switchgear field experience.

The unit was designed specifically with safety in mind. The advantages of a non-catastrophic failure mode which vacuum possesses cannot be realized without the determination of a total design which involves the insulating medium. To this end, the original designs which included oil insulation were abandoned in favor of SF6 insulating gas. This was in keeping with the concept of providing a controlled non-combustible insulating medium within the tank. There have been no eventful failures of this equipment to date.

The use of SF6 insulating gas has provided additional benefits in the way of compactness and light weight. Based on the increased costs of floor space, there is a greater reluctance on the part of the user to give up this valuable area for housing large electrical switchgear. VACpac switchgear space requirements are minimal and may be mounted from walls or ceilings. Special building requirements for liquid containment or combustibles would not apply to an SF6 insulating medium. Compactness also permits the use of VACpac switchgear in manholes or vaults, since installation is possible through the access openings.

Technical Data 285-30Effective April 2014Supersedes May 1999

The hermetically sealed stainless steel unit provides a controlled atmosphere which is corrosion resistant and maintenance free. A positive SF6 gas pressure is only to assure a controlled environment. In the unlikely event of a loss of pressure in a unit filled with SF6 gas, the electrical ratings would not change since SF6 gas is heavier than air. For the remote possibility of a complete loss of SF6 gas, only the BIL would change and all other electrical ratings would remain the same.

Vacuum “bottle” integrity is assured by rigid quality control inspections. The industry operating record has been excellent in this regard. The SF6 gas insulation provides excellent switching redundancy. Theoretically, a loss of vacuum in the VACpac interrupter would cause a reduced ac withstand test voltage, but all other electricals would be functional due to the SF6 environment.

VACpac designs include a short operating stroke requiring little force. This permits the use of a wide variety of remote and automatic operators if desired initially or as a retrofit program. This provides the flexibility and sophistication in switching which is normally obtained with more costly circuit breakers.

Interrupter design characteristicsVacuum arc interruption at high voltages became a commercial realization in the 1960s. Technical refinements created a vacuum atmosphere that does not degenerate from switching operations.

The current in any arc is carried by highly ionized, extremely hot gases. In air, oil, and SF6 interrupters, this gas is created by the decomposition of the interrupting medium. In a vacuum interrupter, this gas is composed almost entirely of metal vapor evaporated from the contacts. As a result, very little arcing takes place and the dielectric strength is recovered in a matter of microseconds. This rapid recovery of dielectric strength accounts for vacuums outstanding current interrupting ability and its ability to withstand high rates of rise of recovery voltages.

Due to this high dielectric recovery, little contact separation (approximately 3/8”) is required and compact, low-powered actuating mechanisms are employed. The low energy arc produced in the vacuum interrupter is quickly extinguished and controlled by contact design. This results in very little contact material being vaporized and the sealed ceramic interrupter housing remains permanently clean.

To operate the switch requires only a short (3”) push to close - pull to open. The mechanism is an overtoggle type to provide a quick and positive make-and-break action. VACpac switchgear can be operated manually or automatically with a choice of controls and accessories. All VACpac controls and components are top mounted. When using automatic controls, positive current interruption can be accomplished in a maximum of 5 cycles; this includes arcing and mechanical operating times.

ConstructionVACpac switchgear are of completely welded construction to provide a hermetically sealed tank enclosure. The tank is made from corrosion resistant 300 series stainless steel. The operating shaft is of stainless steel and the handle is of brass. A standard Schrader filter valve is used to fill the tank with inert non-corrosive sulfur hexafluoride insulating gas. A pressure gauge is provided to monitor internal pressure conditions. The tanks are provided with lifting eyes and hold down installation tabs.

The vacuum interrupter contacts are housed within a glass-ceramic “bottle.” A vacuum of 10-7 torr is pulled in the “bottle” and the unit is tested for vacuum at least four (4) separate times before shipment to the field. This testing is provided to ensure a life in excess of twenty (20) years on the “bottle.”

The interrupter contacts are made from a copper alloy to prevent contact welding. The alloy material has a high vapor pressure which is effectively used to reduce “current chopping.”

A stainless steel vapor condensing shield in the “bottle” performs the function of trapping all the metal vapor produced by the arc. This serves to keep the inner surface of the “bottle” free of any possible contamination and preserves the steady state electrical ratings.

A stainless steel bellows within the “bottle” is attached to a movable external terminal and permits the contacts to be switched while maintaining a vacuum. The bellows has an independent protective shield and has a fatigue life of 10,000 operations. Contact separation in the open position is approximately 3/8”.

The movable vacuum “bottle” terminal is secured to a patented toggle mechanism support casting. This mechanism provides for quickmake, quick-break switching with a positive over toggle travel. The operator switching force required is approximately 35 lbs.

An external operating shaft is used to perform the switching function; push to close, pull to open. The tank seal for this linear switching motion is obtained by means of a movable beryllium copper bellows which is welded to the tank. A secondary seal system is used to ensure the integrity of this bellow. A locking gasp is provided to padlock the operating handle in the open or closed switched position.

Welded universal bushing wells are used to terminate 200 A circuit ways and welded universal stud bushings for 600 A ways. These will accept standard 200 and 600 A EPDM rubber connectors. All operating equipment is top mounted on the VACpac tank. Appropriate nameplate and schematic diagrams are secure to the tank top.

InstallationVACpac switchgear are provided with hold down tabs for mounting purposes. VACpac switchgear are not position oriented and may be mounted on the floor, wall, or ceiling. VACpac switchgear weights may be obtained from “Physical Specifications” (see page 10). It is suggested that VACpac switchgear be bolted in place in submersible environments or the unit will float if the vault or manhole becomes flooded.

Cable terminal attachments to the VACpac switchgear are accomplished with EPDM rubber type connectors. Standard VACpac switchgear are provided with universal bushing wells at 200 A which will accept bushing inserts and universal stud connectors at 600 A which will accept elbow type connectors. These terminations provide for circuit testing, circuit isolation (visible gas) and/or cable grounding.

Paper insulated lead covered (PILC) type cables require special terminations. Consult factory for details.

For long life operations, cable training and terminating should be carefully planned. Lead sheath cables in ducts may be subjected to movement from repeated cyclic loading; if not properly terminated this cable movement could impose excessive stresses on the termination. Extensive unsupported cable weight can also create an excessive strain on the termination. Finally, a momentary fault current can cause cables to produce a “whip action” on unsupported cables which could transmit a shock wave to the terminations. For these reasons, the following recommendations should be considered when terminating cables to equipment.

1. Use URD type concentric cables to terminate at the elbows where possible.

2. Train the cables to enter the elbows along the center axis of the elbow cable cavity as closely as possible.

3. Support the cable 3’ to 4’ from the elbow termination or as specified by the elbow supplier.

4. When solid dielectric lead sheath cables in ducts are used, circle the manhole with the cable before terminating at the switch. This will provide an expansion “U” bend for this cable type.

Features1. Saftoy — Operation is in a self contained fireproof medium—

with elbow terminations—with remote switching options.

2. CNmpaco — Accomplished with a vacuum switching medium and an SF6 self-contained operation medium—largest unit fits through manhole openings—volume is approximately 1/5 that of equivalent oil switches.

3. Mainotnanct Frtt — All switches, mechanism and bus work hermetically sealed within a corrosion resistant 300 series stainless steel enclosure in an inert SF6 environment. The vacuum interrupter housed in a sealed environment is essentially maintenance free throughout its lifetime.

4. Idtal Swioching — Vacuum arc interrupters are fast, efficient, quiet, and not susceptible to the danger of contamination from load switching arcs, lightning, or other surges. When closed an ideal conductor, when open an ideal insulator. Contact design prevents current chopping.

5. Minimizt Liabilioits — Nonflammable insulating SF6 gas will not support combustion in the event of a short circuit inside the switch. This will guard against possible costly liabilities relative to adjacent electrical apparatus, private property, high-rise buildings, schools, extended outages, etc.

6. Lighowtigho — Estimated at approximately 100 lbs. per three-phase way or 1/7 that of an equivalent oil switch.

Switch accessoriesPtrmantno dial oypt SF6 gas prtssurt gaugt

A small and relatively inexpensive pressure gauge is standard with all VACpac switches for convenience in checking and assuring proper SF6 gas pressure surrounding the vacuum bottles. The 2” diameter gauge is quite visible and is located on top of the VACpac switchgear with the switch operating handles and controls.

VACpac manual stltcoNr swioch inotrlNck

A simple mechanical interlock is available for VACpac switches where it is desirable to prevent simultaneous closure of two switched ways. This device blocks the second handle in the open position when one handle is closed. Operation is automatic, and permits easy switch operation, even with a hookstick.

VACop operators for VACpac switchesAll VACpac switches include an operating shaft for switching control. A 3” linear movement of the operating shaft is required to cause the vacuum interrupter to perform a switching function, push to “close” and pull to “open.”

The unique mechanical requirements for switching provide for a wide variation of switching control systems. Switching can be accomplished manually and/or automatically, at or remotely from the VACpac switch. Available controls include electrically controlled or mechanically controlled remote switching. These control systems are housed in separate switch panels and connected to the operators by means of appropriate cable controls. Switching intelligence for automatic switching comes from standard relay* packages, and/or Sigma Fault Detector, and/or Elbow Potential Voltage Sensing Signals.* May be coordinated for fault, voltage, ground, load, temperature, pressure, or differential relay

schemes.

There are six (6) basic operators which can be coupled to any operating shaft on a VACpac switch. These operators may be used singly or in combination depending on the switching requirements; consult the operator application guide for assistance. The operators are identified as follows:

VACNp I - A 240 Vac linear electric motor operator.

VACNp III - A single shot “open” stored energy spring operator with manual reset.

VACNp IV - A manual remote cable operator.

VACNp VI - A 48 Vdc battery-powered solenoid operator.

Note:N Battery powered operations require ac control power for battery charger circuit.

VACpac switch operationsVACNp I NptraoNr funcoiNn

VACop I operator is basically used for automatic transfer switching for critical loads. This unit operates in a minimum of five (5) cycles which includes mechanical switching and arcing times. VACop I operator may also function as an electrical remote pushbutton control close/open switch with or without the automatic transfer system included. Control voltage is 240 Vac

DtscripoiNn

VACop I operator is a direct drive linear motor connected directly to the VACpac operating shaft by means of a pinned coupling. The unit is a 6 horsepower operator requiring 240 Volt 30 A source. For automatic transfer operating 2 VACop I units are employed. One VACop I operator may be used for each switched circuit with a maximum of 4 per VACpac unit.

The removable operator housing is a stainless steel cylinder and is locked in place by means of 2 camtype clamps. A transparent dome, secured to the top of the cylindrical housing, provides a visual indication of the switch in either the closed or open positions. A ring handle on the motor shaft projects above the motor so that with the housing removed, the VACpac can be operated manually or with a hot stick. The housing is completely sealed for submersible operations when secured to its base with the cam clamps.

Controls include modular electrical switching panels housed within a gasketed control cabinet. Pushbuttons with LEDs permit local operation and position indication of the VACpac unit. With automatic transfer controls, a “manual-off-auto” switch permits a local pushbutton switching operation which overrides the automatic controls when on “manual.” A standard 10 foot neoprene-jacketed control cable is used to connect the VACop I operator with the control cabinet (other control cable lengths much be specified). However, when considering voltage drop, source voltage to the operator motor must be held between 230 and 250 Vac to perform a switching function.

AuoNmaoic CNnorNls

Voltage sensing for automatic transfer controls is from potential transformers or from more economical Elbow Potential Devices (EPD). Intelligence for switching is by means of standard relays housed within the control cabinet.

VACNp III NptraoNr funcoiNn

Complete three-phase switching of circuits even for faults is becoming more popular in order to avoid the potential hazards involving: 1) ferroresonance, 2) single-phasing of three-phase motors, 3) circulating currents in some three-phase transformers as from a single-phase fuse operation.

VACop III operator in conjunction with a special 12 kA rated VACpac Fault Interrupter Switch will automatically clear a system fault in 5 cycles (excluding relay time). The unit will perform a single shot tripping operation which must then be manually reset. VACop III operator is available for 15, 25 and 35 kV operating systems. It is especially effective where fuses are difficult to coordinate or install. VACop III operator may also be used for remote pushbutton load interrupting applications.

DtscripoiNn

VACop III operator is a spring charged “stored energy” operator. It must be used on a VACpac unit equipped with the optional 12 kA vacuum interrupter. The operator is connected directly to the VACpac unit operating shaft by means of a pinned coupling. Fault sensing is with either overcurrent relays and CTs. A relayed trip signal is applied to the solenoid circuit which causes the spring to release and open the switch. Pulling the handle atop the VACop III operator resets the spring; a force of 65 lbs. is required to move the handle 3 inches to reset the unit. Pushing the handle atop the operator closes the switch and “arms” the tripping control circuit. A wide range of ac and dc solenoid control voltages is available. The unit is of a trip free design; it will trip when closing into a fault. The removable operator housing is a stainless steel cylinder and is locked in place by means of 2 camtype clamps. A transparent dome provides a visual indication of the switch in either the closed or open (trip) positions; a trip indicator is located under the handle. The housing is completely sealed for submersible operations when secured to its base with the cam clamps.

AuoNmaoic CNnorNls

VACop III operator controls perform an automatic trip operation in 5 cycles; this does not include relay time. The power source for automatic tripping controls may be from one of two systems:

A. Capacitor Discharge Trip Control—Energy from a charged capacitor is used to energize the solenoid and cause the VACop III operator to trip open. Energy storage time after power loss is 5+ hours; life expectancy is 10+ years.

B. Battery Trip Control—Energy from the battery is used to energize the solenoid and cause the VACop III operator to trip. Energy stor-age time after power loss is 5+ days; life expectancy is 2+ years.

The intelligence required to monitor and provide the trip signal is from:

A. Conventional Overcurrent Relays—Used in conjunction with “doughnut” or window type conventional current transformers. May be required for system coordination purposes.

Note:N Trip Control system above requires nominal 120 Vac for charging power which is normally supplied by the user. Specify if 120 Volt source is not available.

VACNp IV NptraoNr funcoiNn

VACop IV operator is a mechanical remote control operator. It can be used to perform mechanical open/close switching through a highly efficient direct connected roller bearing control cable.

Remote automatic switching can be performed in cooperation with VACop III operator.

DtscripoiNn

VACop IV operator consists of flexible stainless steel tubing connected directly to the VACpac operating shaft at one end and with a switch handle connected to the other end. Switching consists of a 3 inches push on the switch handle to “close” and a similar pull action to “open.”

The cable consists of a sliding center race sandwiched between two ballbearing races. The two rows of balls permit the center race to roll between the two outer races with minimum friction resistance. The mechanical efficiency approaches 100% on short runs (thru 50 feet). On a 660 feet run with 2000° of bends the mechanical efficiency is approximately 95%. Cable lengths are available in 5 feet increments through 50 feet. For longer runs, consult factory.

The operating end of VACop IV operator is available connected to:

A. A portable switch stand for 1, 2, 3, or 4 control cables.

B. A fixed handle mount for handhole or similar type installations.

C. A control cabinet for manual operation.

D. A control cabinet for automatic operation.

VACop IV operator is made from corrosion resistant materials and requires no maintenance or lubrication. The unit may be operated where ambient temperatures range from -65 °F to +450 °F. It may also be located in a submersible environment. VACop IV operator exceeds the switching life of the VACpac unit and therefore complements the sophistication of the VACpac interrupter with its advanced design concept.

VACNp VI NptraoNr funcoiNn

The VACop VI operator is a state-of-the-art electro-mechanical operator designed for fault-interrupting, automatic fast transfer systems, including the Fault Interrupting Line Sectionalizer (FILS) used with Kearney VACpac switchgear. It combines the best features of the earlier VACop I, II, III, and V operator models with the very fast operation of a solenoid drive system. It has been specifically designed for use where operating speed and long-term reliability are essential.

DtscripoiNn

The VACop VI operator 48 Vdc solenoid moves the switch shaft. The operator is attached to the VACpac with two machine bolts. The solenoid has separate “open” and “closed” coils. Microswitches are located below the motor. Switches provide separate indication of “open” and “closed” positions. The VACop VI operator is totally SCADA compatible and is suitable for remote control. The machine base of the operator has a watertight control cable hub.

The operating eye allows manual or hookstick operation in case of any emergency. Operating time is less than five (5) cycles.

The operator has been life tested in excess of 10,000 open/close operations. After loss of ac for one week, the unit will still successfully operate in excess of 1200 operations.

RVAC pad-mounted switchgear offers the superior performance of vacuum loadbreak interruption for switching underground distribution systems. Service-proven vacuum interrupters combine with an interrupting mechanism designed specifically for repetitive switching duty to provide a unit ideally suited to such applications as industrial parks and shopping malls where frequent switching is required. Vacuum interrupters offer the further advantages of long life in repetitive service, low maintenance, quiet operation, and high interrupting ratings.

To further serve these loads, RVAC pad-mounted switchgear offers 600 amp main line switching capability and current-limiting fuse protection. RVAC vacuum pad-mounted switchgear is available in single- and three-phase units in ratings of 15, 25 and 35 kV.

The low profile of RVAC pad-mounted switchgear blends into landscaping and is unobtrusive. Deadfront construction is tamper-resistant, and provides a high margin of safety for utility personnel and the general public.

All internal energized parts are insulated in either oil, SF6 gas or the more environmentally desirable and less flammable Envirotemp™ FR3™ and E200 fluid alternatives.* Prior to shipment, the switchgear is filled with the specified insulating medium, eliminating both field filling and the resultant danger of contamination.

RVAC switchgear and components are designed in conformance with IEEE Std C37.74™-2003 standard.

Switching is easily accomplished with a simple push-pull operating lever that moves in and out. The lever can be padlocked in the open or closed position.

A wide selection of current-limiting fuse options is available with amperage ratings and coordination curves to meet your system requirements.

Vacuum inotrrupotr

Vacuum interruption offers a number of advantages in service, reliability and maintenance. The RVAC interrupter offers many times the number of switching operations in a lifetime compared to an air or oil interrupter. Contacts are hermetically sealed, eliminating any source of contamination. Vacuum interruption is fast—on the first current zero. Arcing is minimized. The RVAC interrupter is restrike-free. The dielectric strength of the contact gap recovers much more rapidly than the recovery voltage can rise, therefore eliminating restriking.

Vacuum interrupters from Eaton's Cooper Power Systems (see Figure 2) have been in service since 1983 and have established a superior record of field performance.

Inotrrupotr mtchanism

The advantages of vacuum interruption extend to the interrupter mechanism. The short contact stroke minimizes the mass being moved and therefore mechanical shock. This in turn permits a substantial reduction in the size and total weight of the interrupter assembly.

As a result, the interrupter mechanism for RVAC switchgear is simple, dependable and easy to operate. The operating lever (Figure 3) requires only an easy push or pull action to close or open, and the switch can be padlocked in either position. A key interlock is available for added security.

Currtno-limioing fust prNotcoiNn

For fault protection with RVAC oil-insulated units, Eaton's Cooper Power Systems offers a complete line of fuses available for pad-mounted switchgear. Consult Catalog Section 240-82, ELSG Full-Range Current-Limiting Fuse for fuse ratings and catalog numbers.

Cabinto cNnsorucoiNn

The deadfront, non-ventilated, tamper-resistant construction of RVAC switchgear makes it suitable for operation in areas subject to excessive moisture, occasional flooding* and blowing snow. Additional sealing is provided by the Buna-N rubber gasket in the bolted cover (liquid-filled units only-SF6 covers are welded in place.) RVAC pad-mounted switchgear consists of a sealed insulation tank which houses energized components, and separate main and tap compartments. The main compartment, located at the front of the tank, houses the source bushings and source switches, and has a minimum depth of 22 inches when provided with 600 A bushings. At the rear of the tank, the tap compartment contains tap bushings, tap switches if specified, and fuses. It has a minimum depth of 16 inches when provided with 200 A bushing wells.

Split side-hinged doors are provided for both compartments, with door stops for each section. Fused units have swing-up doors in lieu of the standard side-hinged door. Door hinges are equipped with stainless steel pins. A door extender allows both source and tap doors to be opened at the same time. Doors are secured with recessed stainless steel pentahead bolts, with provisions for padlocking.

Recessed lifting provisions are provided for a balanced lift.
