Global Modular UL Range

Description

Overview on worldwide standards

UL and IEC differ fundamentally. The IEC standards for the IEC market merely specify

the minimum safety requirements of a device or system. Technical details of the safety

requirements constructional implementation are up to the manufacturers.

In contrast, the standards for the American market are far more detailed. Depending on

the standard, the required process may be monitored from product design to product

production down to application, mounting and operation.

Below figure shows the influence areas where IEC or UL is unique in the market

or has more influence on it.

The current GLOBAL UL/IEC Modular DIN rail range that is shown in this

document allows any OEM to work at Global level in any market.

Description

Equipment Protection Standards.UL 1449 3rd editionThe objective of UL 1449 has always been to increase safety in terms of surge protection. Thus, major changes have recentlybeen made to the surge protection standard. The latest edition, known as UL 1449 3rd edition, was published on September 29, 2006 and took effect September 2009, and is now also an ANSI standard. A revision was made on February 8, 2011. Prior to UL 1449 3rd edition taking effect, the devices with this standard covers what were known as transient voltage surge suppressors standard (TVSS), operating on power circuits not exceeding 600V. With the inception of the 3rd edition, these devices are now known as surge protective devices (SPDs), and may operate on power circuits not exceeding 1000V. This new designation moves the UL standard closer to the International designation and to IEC standards. The new edition is now renamed UL standard for safety for surge protective devices, UL 1449.

In the IEC market, Surge Protection Devices should comply with following standards:

IEC 61643-11-12IEC 61643-11:2011 is applicable to devices for surge protection against indirect and direct effects of lightning or other transient overvoltages. These devices are packaged to be connected to 50/60Hz a.c. power circuits, and equipment rated up to 1 000V r.m.s. Performance characteristics, standard methods for testing and ratings are established. These devices contain at least one nonlinear component and are intended to limit surge voltages and divert surge currents. This first edition of IEC 61643-11 cancels and replaces the second edition of IEC 61643-1 published in 2005.

IEC62305-1-2-3-4 – LP (Application of SPD’s)The section -1 contains information about the risk posed by lightning, lightning characteristics, and the parameters derived therefrom for the simulation of the effects of lightningSection - 3: Risk management in accordance with IEC 62305-2 (EN 62305-2) uses risk analysis to first establish the necessity for lightning protection The section - 3: Physical damage to structures and life hazard deals with the protection of buildings and structures and persons from material damage and life-threatening situations caused by the effect of lightning current or by dangerous sparking, especially in the event of direct lightning strikes.Section - 4: Electrical and electronic systems within structures deal with the protection of buildings and structures with electrical and electronic systems against the effects of the lightning electromagnetic impulse.

LV Energy Management Power Analyzers standards.ANSI/UL 508. Industrial Control EquipmentThese requirements cover industrial control devices, and device accessories thereto, for starting, stopping, regulating, controlling, or protecting electric motors. These requirements also cover industrial control devices or systems that store or process information and are provided with an output motor control function(s). This equipment is for use in ordinary locations in accordance with the National Electrical Code, NFPA 70. These requirements cover devices rated 1500 volts or less. Industrial control equipment covered by these requirements is intended for use in an ambient temperature of 0 - 40°C (32 - 104°F) unless specifically indicated for use in other conditions. This is the basic standard used to investigate products in the Power and net analyzers which are under UL Power Circuit and Motor-mounted Apparatus category.

IEC-61000-4-30 StandardIEC 61000-4-30 defines measurement methods for 50Hz and 60Hz power quality instruments. The Power Standards Lab was deeply involved in developing this standard, and continues to guide it with on-going revisions and updates.

This standard ensures that different PQ instruments use the same definitions, and measurement techniques, for various power quality parameters: sags/dips, swells, frequency, harmonics, flicker, etc. Older, non-compliant instruments may use their own definitions. As a result, two non-compliant instruments may produce very different readings for the same event. This standard defines three types of Power analyzers A, S and C which will depend on the accuracy of different measurement following the below table:

Parameter Class Influence

Frequency A 42.5-57.5HzS 42.5-57.5HzB 42.5-57.5Hz

It’s is very important for a Global OEM player to know the different net diagrams and Voltage in the different areas. Wiring diagrams according to IEC 60364-1

TT systemIn a TT (Terra-Terra) earthing system, the protective earth connection for the consumer is provided by a local earth electrode, and there is another independently installed at the generator. There is no 'earth wire' between the two. The fault impedance is higher, and unless the electrode impedance is very low indeed, a TT installation should always have an RCD as its first isolator. The big advantage of the TT earthing system is that it is clear of high and low frequency noises that come through the neutral wire from connected equipment. TT has always been preferable for special applications like telecommunication sites that benefit from the interference-free earthing. In locations where power is distributed overhead and TT is used, installation earth conductors are not at risk should any overhead distribution conductor be fractured by, say, a fallen tree or branch. In pre-RCD era, the TT earthing system was unattractive for general use because of its worse capability of accepting high currents in case of a live-to-PE short circuit (in comparison with TN systems). But as residual current devices mitigate this disadvantage, the TT earthing system becomes attractive for premises where all AC power circuits are RCD-protected. The TT earthing system is used throughout Japan, with RCD units in most industrial settings. This can impose added requirements on variable frequency drives and switched-mode power supplies which often have substantial filters passing high frequency noise to the ground conductor.

Description

TN-S systemIn a TN earthing system, one of the points in the generator or transformer is connected with earth, usually the star point in a three-phase system. The body of the electrical device is connected with earth via this earth connection at the transformer.The conductor that connects the exposed metallic parts of the consumer's electrical installation is called protective earth (PE or Ground). The conductor that connects to the star point in a three-phase system, or that carries the return current in a single-phase system, is called neutral (N). In TN-S system PE and N are separate conductors that are connected together only near the power source. This arrangement is a current standard for most residential and industrial electric systems particularly in Europe.

TN-C systemIn that case, a combined PEN conductor fulfils the functions of both a PE and an N conductor.

The majority of modern installations in both the US and Canada feature the following kind of power distribution system.

Single phaseSingle-phase power distribution is widely used especially in rural areas, where the cost of a three-phase distribution network is high and motor loads are small and uncommon.

A split-phase or single-phase three-wire system is a type of single-phase electric power distribution. It is the AC equivalent of the original Edison three-wire direct current system. Its primary advantage is that it saves conductor material over a single-ended single-phase system while only requiring single phase on the supply side of the distribution transformer.This three-wire system is common in countries with a standard phase-neutral voltage of 120V. It is commonly used in North America for single-family residential and light commercial applications.In North American electrical codes, the split-phase distribution may be carried to the outlet receptacles. Two 120 volt devices may be plugged into a duplex receptacle that connects one neutral wire to both outlets. This saves the cost of one wire back to the panelboard. Such multiwire branch circuits have special rules in the electrical codes to ensure they are safely applied.

Delta systemDelta connected power is developed from three, independent transformer or generator windings that are connected head to toe. There is no single point common to all phases. Delta power is named after the schematic resemblance of the windings to the Greek letter Delta.Delta connected power only has a single voltage level available: the Phase to Phase voltages. Other voltages can be obtained only by using step-up or step-down transformers.Equipment designed to operate from Delta connected power, such as air conditioners or motors, can also operate from Wye connected power without a problem, since the Phase to Phase voltages are available in both systems. However, equipment that requires Wye connected power cannot operate from a Delta connected source. The Phase to Neutral voltages are not available. A special isolation transformer, designed to convert Delta to Wye, is used in this case.

Grounded Wye systemWye connected power is developed from three, independent transformer or generator windings that are connected at a common point, called a neutral or star point. Wye power is named after the schematic resemblance of the windings to the Greek letter Wye (Y).Wye connected power has two different voltages available. The Phase to Phase voltage is the main system voltage (typically 208V AC or 480V AC in the United States). The Phase to Neutral voltage is also available, and is typically used for small single phase loads (120V AC or 277V AC).

It is common to find either Delta or Wye connected power within North American facilities. If a piece of equipment is designed to operate from a Wye connected source, using a Delta source can cause safety, reliability, and operation problems.

In these cases, a Delta-Wye transformer, such as found in many power conditioning devices, will convert the facility Delta connected power to a Wye connected source. Unfortunately, it is not always easy to determine which type of power is found within a particular facility until the actual equipment installation is underway. As a result , if equipment requires Wye connected power, adding a Delta-Wye transformer makes sense to improve system performance and to minimize unexpected site problems.

High-Leg DeltaThis is a three-phase 240V delta connected system, in which one winding of the transformer has a center tap which is connected to ground and used as the system neutral. This allows a single service to supply 120V for lighting, 240V single-phase for heating appliances, and 240V three-phase for motor loads (such as air conditioning compressors). Two of the phases are 120V to neutral, the third phase or "high leg" is 208V to neutral.

Multiwire systems split more than two ways are possible with both AC and DC but have the significant disadvantage that no matter which point is tied to ground some of the wires will have a higher earth relative voltage than the utilisation voltage; therefore, such systems are not used in normal power distribution.

SelectivityAn installation with some protective devices in series (a protective device must be placed at the point where a reduction of the cross sectional area of the conductors or another change causes modification in the characteristics of the installation) is considered as selective when, in

the event of short-circuit, the installation is interrupted only by the device which is immediately upstream of the fault point. Selectivity is ensured when the characteristic time/current of the upstream MCB (A) is above the characteristic time /current of the downstream MCB (B). The let-through energy (I2t) of the downstream protective device shall be lower than the one of the upstream protective device. Selectivity may be total or partial.

Total selectivity: Selectivity is total in the event of a short-circuit fault and only disconnects the protective device B immediately upstream of the fault point.

Partial selectivity: selectivity is partial when the no disconnection of the protective device (A) is ensured only up to a certain level of the current. In figure below is shown that selectivity is total up to the point of overlapping curves. From this point total selectivity can not be assured and selectivity curves based on tests by the manufacturer should be consulted.

Please, check the ElfaPlus Technical Catalogue to review selectivity tables with Moulded Case Circuit Breakers upstream and IEC MCBs downstream.

Association (back-up protection)Association consist the use of an MCB with lower breaking capacity than the presumed one at the place of its installation. If another protective device installed upstream is co-ordinated so that the energy let-through by these two devices does not exceed that which can be withstood without damage by the device placed downstream and the conductor protected by these devices. In the event of short-circuit, both protective devices will disconnect, therefore the selectivity between them is considered as partial. Association reduces the cost of the installation in case of high short-circuit currents.

To obtain association between a breaker and a protective device, several conditions linked to the components characteristic must be fullfilled. Those have been defined by calculation and testing.

Please, check the ElfaPlus technical catalogue to review back-up tables with Moulded Case Circuit Breakers upstream and IEC MCBs downstream.

Use in DCSelection criteria

The selection of an MCB to protect a D.C. installation depends on the following parameters:

- The nominal current

- The nominal voltage of the power supply, which determines the number of poles to switch the device

- The maximum short-circuit current, to determine the short-circuit capacity of the MCB

- Type of power supply In the event of an insulation fault, it is considered as an overload when one pole or an intermediate connection of the power supply is connected to earth, and the conductive parts of the installation are also connected to earth.

Insulated generator

Generator with centre point earth connection

In the event of short-circuit between any pole (+ or -) and earth, there is a Isc<Isc max because the voltage is Un/2. If the fault occurs between the two poles there is a short-circuit in the installation which value depends on the impedance of the installation as well as the voltage Un. Each polarity shall be provided with the necessary number of poles to break the maximum short-circuit at Un/2.

Use of standard MCB in DC (acc. to IEC 60947-2)

For MCB’s designed to be used in alternating current but used in installations in direct current, the following should be taken into consideration:

- For protection against overloads it is necessary to connect the two poles to the MCB. In these conditions the tripping characteristic of the MCB in direct current is similar in alternating current

- For protection against short-circuits it is necessary to connect the two poles to the MCB. In these conditions the tripping characteristic of the MCB in direct current is 40% higher than the one in alternating current.

TECHNICAL PAPER


SelectivityAn installation with some protective devices in series (a protective device must be placed at the point where a reduction of the cross sectional area of the conductors or another change causes modification in the characteristics of the installation) is considered as selective when, in

the event of short-circuit, the installation is interrupted only by the device which is immediately upstream of the fault point. Selectivity is ensured when the characteristic time/current of the upstream MCB (A) is above the characteristic time /current of the downstream MCB (B). The let-through energy (I2t) of the downstream protective device shall be lower than the one of the upstream protective device. Selectivity may be total or partial.

Total selectivity: selectivity is total in the event of a short-circuit fault and only disconnects the protective device B immediately upstream of the fault point.

Partial selectivity: selectivity is partial when the no disconnection of the protective device (A) is ensured only up to a certain level of the current. In figure below is shown that selectivity is total up to the point of overlapping curves. From this point total selectivity can not be assured and selectivity curves based on tests by the manufacturer should be consulted.

Please, check the ElfaPlus technical catalogue to review selectivity tables with Moulded Case Circuit Breakers upstream and IEC MCBs downstream.

TECHNICAL PAPER


Association (back-up protection)Association consist the use of an MCB with lower breaking capacity than the presumed one at the place of its installation. If another protective device installed upstream is co-ordinated so that the energy let-through by these two devices does not exceed that which can be withstood without damage by the device placed downstream and the conductor protected by these devices. In the event of short-circuit, both protective devices will disconnect, therefore the selectivity between them is considered as partial. Association reduces the cost of the installation in case of high short-circuit currents.

To obtain association between a breaker and a protective device, several conditions linked to the components characteristic must be fullfilled. Those have been defined by calculation and testing.

Please, check the ElfaPlus technical catalogue to review back-up tables with Moulded Case Circuit Breakers upstream and IEC MCBs downstream.

Use in DCSelection criteria

The selection of an MCB to protect a D.C. installation depends on the following parameters:

- The nominal current

- The nominal voltage of the power supply, which determines the number of poles to switch the device

- The maximum short-circuit current, to determine the short-circuit capacity of the MCB

- Type of power supply In the event of an insulation fault, it is considered as an overload when one pole or an intermediate connection of the power supply is connected to earth, and the conductive parts of the installation are also connected to earth.

Insulated generator

In insulated generators there is no earth connection, therefore an earth leakage in any pole has no consequence. In the event of fault between the two poles (+ and –) there is a short-circuit in the installation which value will depend on the impedance of the installation as well as of the voltage Un. Each polarity shall be provided with the appropriate number of poles.

Generator with one earthed pole In the event of a fault occuring in the earthed pole (-) there is no consequence. In the event of a fault between the two poles (+ and -) or between the pole + and earth, then there is a short-circuit in the installation which value depends on the impedance of the installation as well as of the voltage Un. The unearthed pole (+) shall be provided with the necessary numbers of poles to break the maximum short-circuit.

People protection. Ground fault protection

Our RCCB and RCBO range follows the UL 1053 UL Standard "Safety for Ground-Fault Sensing and Relaying Equipment" and it has the approval mark, making possible to

install in certain circuits inside Global OEM’s machinery. These requirements cover ground-fault cur-rent sensing devices, relaying equipment, or combinations of ground-fault current sensing devices and relaying equipment or equivalent protection equipment for use in ordinary locations that will operate to cause a disconnecting device to open all ungrounded conductors at predetermined values of ground-fault current, in accordance with the National Electrical Code, ANSI/NFPA 70.Our FPA RCCB range can be considered Class I ground-fault protection device since it is one that does not incorporate means to prevent opening of the disconnecting means at high levels of fault current and is intended for use with the following: ✔ Circuit breakers,

✔ Fused circuit breakersBoth ranges, FPA (RCCB) and DPA100 (RCBO) are tested and recognized under UL1053, as gound fault sensing and relaying equipments.

What is an RCCB?

The RCD (Residual Current Device) is a device which intends to protect people against indirect contact, the exposed conductive parts of the installation being connected to an appropriate earth electrode. It may be used to provide protection against fire hazards due to a persistent earth fault current, without the operation of the overcurrent protective device. RCD's having a rated residual operating current not exceeding 30mA are also used as a means for additional protection in case of failure of the protective means against electric shock (direct contact).

Working principleThe main components of a RCD are the following:✔ The core transformer: which detects the earth

current fault.✔ The relay: when an earth fault current is

detected the relay reacts by tripping and opening the contacts.

✔ The mechanism: Element to open and close the contacts either manual or automatically.

✔ The contacts: To open or close the main circuit. The RCD constantly monitors the vectorial sum of the current passing through all the conductors. In normal conditions the vectorial sum is zero (I1+I2=0) but in case of an earth fault, the vectorial sum differs from zero (I1+I2=Id), this causes the actuation of the relay and therefore the release of the main contacts.

52

TECHNICAL PAPER


Technical Data


RCD’s classification according to EN 61008/61009RCD’s may be classified according to:The behavior in presence of dc current (types for general use).

✔ Type AC: The type AC RCDs are designed to release with sinusoidal residual currents which occur suddenly or slowly rise in magnitude.

✔ Type A: Certain devices during faults can be the source of non-sinusoidal earth leakage currents (DC components) due to the electronic components e.g.: diodes, thyristors ...

The type A RCD’s are designed to ensure that under this conditions the residual current devices operate on sinusoidal residual current and also with pulsating direct current(*) which occur suddenly or slowly rise in magnitude.

SelectivityVertical selectivity

In an installation with RCD’s installed in series we need to pay special attention to the vertical selectivity, in order to ensure that in case of earth leakage only the RCD which is immediately upstream of the fault point will operate.Selectivity is ensured when the characteristic time/current of the upstream RCD (A) is above the characteristic time /current of the downstream RCD (B). To obtain vertical selectivity we should take

into consideration the following parameters:The RCD placed at the top of the installation shall be Type S. The residual operating current of the RCCB installed downstream shall have a lower residual operating current than the RCD installed upstream according to:

Horizontal selectivityTo have horizontal selectivity in an installation with RCD’s we need to avoid the use of RCD’s in cascading. Every single circuit of the installation shall be provided with an RCD of the appropriate residual operating current. The connection between the back-up protective device and the RCD must be short-circuit protected (Class II).

Surge overvoltages are spikes that can reach tens of kilovolts during microseconds. Despite their short duration, their high energy content may cause serious problems to equipment connected to the line, from premature aging to destruction, causing disruptions to service and financial loss.

Why protect?

Transient overvoltages are voltage surges that can reach tens of kilovolts with a duration of the order of microseconds. This type of surge can have various different causes, including atmospheric lightning directly striking the external protection (lightning rod) on a building or transmission line or the associated induction of electromagnetic fields on metallic conductors.

TECHNICAL PAPER


It is al so common for non-weather phenomena, such as transformer center switching or the switching off of motors or other inductive loads to cause voltage spikes in adjacent lines.

Voltage surges are not exclusive to power distribution lines but are also common in any line made of metal conductors, such as telephone, communication, measurement and data lines.

The development of technology towards the miniaturization and generalization of electronics in equipment and devices raise the potential risk of surges. In some cases these destroy equipment immediately and in other cases they gradually deteriorate it , shortening its service life. Overvoltage protection is a highly beneficial investment in terms of improvement of equipment life, continuity of service and savings on maintenance costs.

How a protector works.

A surge protective device acts as a voltagecontrolled selector switch and is installed between the active conductors and earth in parallel to the equipment to be protected. When the network voltage is lower than the activation voltage, the protector acts as a high-impedance element, so that no current passes through it. On the other hand, when the network voltage exceeds the activation voltage, the protector acts as a near-zero impedance element, deriving the surge to earth and preventing it affecting the receivers.

Protection parameters according to UL 1449 3rd Ed

Imax: MAXIMUM DISCHARGE CAPACITYMaximum peak current, per phase, in 8/20 μs wave that the protection device is able to withstand.

In: NOMINAL DISCHARGE CURRENTRarting peak current in 8/20 μs wave that the protection device can withstand on 15 occasions without reaching the end of its service life.

VPR: VOLTAGE PROTECTION RATINGThis indicates the maximum residual voltage between the terminals of the protection device during application of an In peak current.

MCOV: MAXIMUM CONTINUOUS OPERATING VOLTAGEThis indicates the maximum effective or direct current voltage that can be permanently applied to the terminals of the protection device.

Type

The new UL 1449 3rd edition places SPDs into five different type categories based on installation location within an electrical system. While type 1, type 2 and type 3 categories refer to different types of SPDs that can be installed at specific locations, type 4 and type 5 categories refer to components used in an SPDs configuration.

Type 1Permanently connected SPDs intended for installation between the secondary of the service transformer and the line side of the service equipment (main panel) overcurrent device, as well as the load side, including watt-hour meter socket enclosures and intended to be installed without an external overcurrent protective device.

Type 2Permanently connected SPDs intended for installation on the load side of the service equipment (main panel) overcurrent device; including SPDs located at the branch panel.

Type 3Point of utilization SPDs, installed at a minimum conductor length of 10 meters (30 feet) from the electrical service panel to the point of utilization. For example cord connected, direct plug-in, receptacle type and SPDs installed at the utilization equipment being protected. The distance (10 meters) is exclusive of conductors provided with or used to attach SPDs.

Type 4Component assemblies – “Component assembly consisting of one or more Type 5 components together with a disconnect (integral or external) or a means of complying with the limited current tests.”

Type 1, 2, 3Component assemblies – “Consists of a type 4 component assembly with internal or external short circuit protection.”

Type 5Discrete component surge suppressors, such is installed to the equipment, the better the protection is. This is a push in the direction of providing stepped protection including external and internal surge protection.

Type

The Integrated TRANQUEL enclosed surge protective device (SPD) is an extensive range of surge protection products. It is designed to be installed at the service entrance, thereby protecting the entire facility from the harmful effects of transient surges.

Over 80% of transient surges are caused by internal sources such as load switching and normal equipment operations. The installation of SAP GEIS range UL 1449 3rd edition pluggable AC DIN rail SPDs will combat these surges and provide protection to valuable equipment and help keep an operation up and running. This new product range is approved as Type 4 recognized components and is usable in Type 2 applications. Installation at branch panels, control panels and terminal equipment is recommended to provide the most complete protection.The SAP range is completed with DC Photovoltaic range UL 1449 3rd edition pluggable in 3 main DC voltage versions: 600, 1000, 1500V DC.

Choosing the correct model

➊ Determine the service voltage. Consult qualified personnel if the facility or operation service voltage is unknown.

➋ Select the SPD maximum continuous operating voltage (MCOV, Uc) The MCOV should correspond to the service voltage. Example: if the service voltage is 480V/240V split phase, an SPD with 320V MCOV will be required. Surge protection devices must also provide a level of protection compatible with the withstand voltage of the equipment. This withstand voltage depends on the type of equipment and its sensitivity. The incoming surge protector may not provide adequate protection by itself, as certain electrical phenomena may greatly increase its residual voltage if cable lengths exceed 10m. A second SPD may be necessary.

➌ The DIN rail range is installed in the Main distribution panel and sub-distribution panel while the Trisquel is used in service entrance.

➍ Remote monitoring (optional): Integrated auxiliary contact for remote monitoring available on models with “C” designation.

What is electrical energy efficiency?

Electrical energy efficiency is understood as the reduction in power and energy demands from the electrical system without affecting the normal activities carried out in buildings, industrial plants or any other transformation process.

Additionally, an energy efficient electrical installation allows the economical and technical optimization. That is, the reduction of technical and economical costs of operation. In short, a study on energy savings and efficiency will involve three basic points:

✔ Support the sustainability of the system and the environment by reducing greenhouse emissions as a result of reducing the energy demand.

✔ Improving of the technical management of the installations by increasing its efficiency and avoiding stoppages and breakdowns.

✔ Reduction of the economical cost of the energy as well as the operating costs of the installations.

From a technical point of view, four basic points are considered in order to have a more efficient electrical installation.

✔ Contract optimizing✔ Measurement systems✔ Demand management

Productivity improving by controlling perturbances and costs.

Basic questions about electrical energy efficiency

With the four basic points explained, we put forth a series of questions on each point. The questions hope to identify the objectives to work on, in order to obtain an efficient electrical installation.

Contract optimizingIs your electric contract the most suitable one for your needs? Do you know that a bad power quality can affects your activities or production processes?

Measurement systemsDo you know how, when and where are you using the electrical energy? Do you really think that all your energy consumed is the most accurate one?

Demand managementCould you reduce the consumption of electrical energy without affecting the processes or activities carried out? Would it be possible to improve the technical effi ciency of your electrical installations?

Produtivity improvingIs there anyway to avoid breakdowns and stoppages on your electrical equipment and installations? Then, could you improve the productivity of your processes?

Outline of a study of electrical energy efficiency

The first step to do in a process of electrical energy efficiency is to carry out an electrical energy diagnosis and audit. In this process, measurements of power and energy will be taken, as well as other variables necessary for making the suitable decisions.Along those lines, two key points should be taken into consideration:✔ What information do we attempt to get from the measurements?✔ Which are the right points to be measured?

In all cases, there is one way to carry out the audit:

Measurements must be taken using MT DIN UL& MT144 UL measuring equipment. These equipment permit storing all the variables selected in their memory (power, energy, etc.). The number of measurements agree with the number of points that are considered to be critical or necessary. Depending on the type of process, the duration of each measurement will be determined. The aim is to represent the true state of the point measured.These equipments permits great flexibility and it also allow to follow up of the energy consumption after the appropriate decisions have been made. It is recommended to study the points where the measurements are taken for the subsequent installation of a fixed measurement system that communicates with the Energyviewer management software.
