Certi ed quality: ISO 9001 and ISO 9002A major assetIn each of its units, Schneider Electric integrates a functional organization whose main role is to check quality and monitor compliance with standards. This procedure is:

uniform throughout all departments,recognized by many customers and approved organizations.

But above all, it is its strict application that has allowed us to obtain the recognition of an independent organization: The French Quality Assurance Association (AFAQ).The quality system for the design and manufacture of MCset is certified to be in conformity with the requirements of ISO 9001 quality assurance standard.

Strict and systematic checksDuring manufacture, each MCset functional unit is subject to systematic routine testing with the aim of checking the quality and conformity of the following features:

measuring of opening and closing speeds,measuring of operating torque,dielectric test,testing of safety systems and interlocks,testing of low voltage components,conformity with drawings and diagrams.

The results obtained are recorded and approved by the quality control department on each devices test certificate.This therefore guarantees product traceability.

Checking SF6 switchgearsealing test,filling pressure test.Checking vacuum switchgear

Each vacuum interrupter, sealed and airtight, is checked for the quality of the vacuum obtained. This pressure measurement is based on the proven magnetron discharge method. Using this sophisticated procedure, measurement is very precise and does not require access to the inside of the bulb, thus not affecting the airtight seal.

Protected environmentSchneider Electric is committed to a long-term environmental approach.All the necessary measures have been taken in conjunction with our services, suppliers and subcontractors to ensure that the materials used in the composition of the MCset equipment do not contain any substances prohibited by the regulations and directives.In order to help you protect the environment and to relieve you of any concerns in terms of stock or dismantling, Schneider Electric Services offers to take back your equipment at the end of its life. MCset has been designed with environmental protection in mind:

the materials used, insulators and conductors are identified, easily separable and recyclable,

the SF6 can be recovered at the end of the equipments life and reused after treatment,

The environmental management system adopted by Schneider Electrics production sites for the manufacture of MCset has been assessed and recognised as conforming to the requirements of the ISO 14001 standard.

MCset internal arcBasic version (gas exhaust) MCset is designed to eliminate the effects of internal arcing in total safety, due to:

metal flaps positioned above the enclosure, which in the case of internal fault, limit overpressure in the compartments.

nonflammable materials used for the cubicle.Internal arc versionMCset is designed to withstand and protect operators in the case of failure due to an internal arc. MCset has been successfully tested using type tests.Protection against internal arcing is available on 25 kA, 31.5 kA, 40 kA and 50 kA ratings.MCset proposes several options to install an internal arc switchboard.

3-sided internal arc protection For an MCset switchboard fitted against a wall, access to the rear of the cubicle is impossible. Internal arc protection on 3 sides is sufficient.

4-sided internal arc protectionIn the case of an MCset switchboard installed in the middle of a room, internal arc protection on 4 sides is necessary in order to protect an operator who goes behind the cubicle.

Installation in a room with limited ceiling height:height exceeding 2.8 m, potential for installing a tunnel above the switchboard to

prevent reflection of hot gases on the ceiling.Ceiling height Tunnel2.8 m < h < 4 m Mandatoryh > 4 m Not mandatory

Internal arcing detector MCset has 2 systems that can detect internal arcing and switch off the power supply so as to limit the fault duration.

electromechanical detectorThis system employs a positive security electromechanical tripping circuit, positioned on the cubicles flap valves. This set transmits the information to the Sepam to give the opening order to the circuit breaker located upstream of the fault.

optic detector (VAMP system)Internal arcing is detected by optical sensors which will measure the light caused by the initiation of arcing. Based on this information, an electronic module, after processing the information, will give the opening order to the circuit breaker located upstream of the fault.

Dependable mechanical control devicesAll operations are carried out from the front face, including access to connections and busbars.The user is guided through icon-diagrams on each front panel making it easy to understand the operating sequence and device status.Interlocks and padlocks prevent operator errors.Several additional levels of security also protect operators:

racking in and out is only possible with the door closed.locking of the MV door open if the LV plug of the circuit breaker is not plug-in.the very extensive set of mechanical and electrical interlocks do not allow operator

error. These can be added to by key locks or padlocks according to specific operating procedures. Each selector can be fitted with one to three padlocks.

all operations are carried out from the front face including access to connections and busbars.

the voltage present indicator is located on the front face of the functional unit, in the immediate vicinity of the earthing switch control.

disarming of circuit breaker when racking out. This function enables the circuit breaker control springs to be disarmed during the extraction operation.

locking of withdrawable part/cable compartment. This function disables the possibility of racking the withdrawable part in if the front panel (cable compartment) is not installed.

Thermal diagnosis systemUseTo reduce maintenance costs in MV substations.It continuously monitors temperature rise using optical fibres and sensors installed at the heart of the sensitive areas.The sensors are located on cable connections and on top MV fuse holders.

PresentationThermal diagnosis is based on the principle of temperature measurement of energized circuits. By using optical fibres, the system doesnt introduce any risks in terms of insulation.It provides:

permanent monitoring of the temperature rise in power circuits at the connections,tripping of a pre-alarm, then an alarm by activating dry contact outputs,indication of the zone and circuit involved.

The standard solution is composed of the MDT module and two probes as described hereunder.

Probes CFO733The optical fibre probes are factory-built assemblies comprising:

3 sensors attached to the power circuit,the optical connections,a connector linked to the module.

This connector incorporates the opto-electrical conversion unit thus eliminating any optical connections when assembling.

MDT106 moduleThe MDT106 electronic module is mounted in the low voltage compartment of the cubicle. It provides the following functions:

monitoring of temperature rise in 2 zones,triggering of the pre-alarm,triggering of the alarm,self-monitoring of the module,self monitoring of the temperature probes.

5 PresentationThe Evolis circuit breaker is used to equip AD1-2-3 and CL1-2-3 cubicles for rated values of 7.2kV to 17.5kV.

High electrical enduranceA magnetic field is applied in the axis of the interrupter contacts.This process maintains the arc in diffuse mode, even at high current values. It ensures optimal distribution of energy over the contact surface and avoids localized temperature rise.The advantages of this technique are:

a very compact interrupter unit,low dissipation of arc energy in the interrupters.

Evolis is in conformity with the highest electrical endurance class (IEC 62271-100: class E2).

High mechanical enduranceThis magnetic field is generated by a patented outside coil which surrounds the contact area. This solution has many advantages:

a simplified and therefore reliable interrupter unit,heavy duty contacts which do not distort during repeated switching operations.

For the first time the control mechanism in a low voltage device is being integrated in a medium voltage circuit breaker. The Masterpact control unit used on Evolis gives us the benefit of a system that has proved its value over more than ten years in hundreds of thousands of installations.Evolis is in conformity with the most demanding mechanical endurance class (IEC 62271-100: class M2).

Undervoltage release (MN)

Undervoltage release (MN)This release unit causes the systematic opening of the circuit breaker when itssupply voltage drops below a value less than 35% of the rated voltage, even if thisdrop is slow and gradual. It can open the circuit breaker between 35% and 70% ofits rated voltage. If the release unit is not supplied power, manual or electrical closingof the circuit breaker is impossible. Closing of the circuit breaker is possible whenthe supply voltage of the release unit reaches 85% of its rated voltage.

Time delay for MNTo eliminate spurious tripping of the circuit breaker when there are brief voltage drops, the MN action is controlled with a time delay. This function is achieved by adding a time delay unit outside of the undervoltage release (MN) circuit (adjustable time delay).This unit is placed outside the circuit breaker and can be inhibited by an emergency stop button to obtain instant circuit breaker opening.

Any tripping due to the Mitop release unit is momentarily indicated by an SDE type changeover contact, provided with the Mitop. This release also includes a coil (reset) enabling remote SDE contact reset.Comment:Use of the Mitop low energy release requires adjustment of the protection relay time delay in order to ensure that the circuit breaker trips between 45-50 ms.

FunctionRemote control enables the remote opening and closing of the circuit breaker. The opening order always takes priority over the closing order.In the event of simultaneous opening and closing orders, the mechanism discharges under no load, without moving the main contacts. The circuit breaker remains in the open position.In the event of latched opening and closing orders, the mechanism carries out anti-pumping function as standard, by blocking the circuit breaker in the open position. Anti-pumping function: after opening on a fault or deliberate opening via the manual or electrical mechanism, the closing order must be interrupted then reactivated to enable reclosing of the circuit breaker.

CompositionThe remote control comprises:

an electrical motor (MCH) equipped with a spring armed CH limit switcha shunt closing release (XF).

Electrical motor (MCH)The electrical motor carries out the automatic rearming of the storage energy springs as soon as the circuit breaker closes. This allows instant reclosing of the device after opening. The arming lever is only used as a backup control in the case of the absence of the auxiliary power supply. An electrical motor (MCH) equipped with a spring armed CH limit switch.This contact indicates the armed position of the mechanism (springs armed).

Undervoltage release (YM)This release unit causes the systematic opening of the circuit breaker when itssupply voltage drops below a value less than 35% of the rated voltage, even if thisdrop is slow and gradual. It can open the circuit breaker between 35% and 70% ofits rated voltage. If the release unit is not supplied power, manual or electrical closingof the circuit breaker is impossible. Closing of the circuit breaker is possible whenthe supply voltage of the release unit reaches 85% of its rated voltage.
