Certifi ed quality: ISO 9001 version 2000A 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 certifi ed to be in conformity with the requirements of ISO 9001 version 2000 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 device’s test certifi cate.This therefore guarantees product traceability.

Checking SF6 switchgearsealing test,fi lling 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 environmentIn 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 identifi ed, easily separable and recyclable,

the SF6 can be recovered at the end of the equipment’s life and reused after treatment,

production sites are certifi ed to ISO 14001.

MCset range Description (cont.)

Make up of an MCset switchboardMCset switchboards are made up of several interconnected functional units.Power connections are made between functional units within a switchboard via a single busbar.The electrical continuity of all metal frames is provided by the connection of each functional unit’s earthing busbar to the switchboard’s main earthing circuit.Low voltage wiring trays are provided in the switchboard above the low voltage control cabinets.LV cables can enter the switchboard through the top or bottom of each functional unit.

Description of a functional unitA functional unit comprises all equipment in the main and auxiliary circuits which together provide a protection function. Each functional unit combines all the components which are required to fulfi l this function:

the cubicle,the protection, monitoring and control system,the withdrawable part.

The cubicleThe cubicle is of LSC2B (Loss of Service Continuity Category) type as defi ned by IEC standard 62271-200, in other words the medium voltage parts are compartmented using metal partitions (PM class) which are connected to earth and which separate:

the busbars,the withdrawable part (circuit-breaker, fuse-contactor, disconnector truck or

earthing truck),MV connections, earthing switch, current sensors and voltage transformers

as required.MCset guarantees a high level of protection of people; when a compartment containing a main circuit is open, the other compartments and/or functional units may remain energised.The low voltage auxiliaries and monitoring unit are in a control cabinet separated from the medium voltage section.Four basic cubicle layouts are offered:

incomer or feeder ADline up bussection CL - GLbusbar metering and earthing TTswitch-fuse feeder DI

MCset switchboard with tunnel

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

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

nonfl ammable 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 fi tted against a wall, access to the rear of the cubicle is impossible. Internal arc protection on 3 sides is suffi cient.

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 refl ection 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 cubicle’s fl ap 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 specifi c operating procedures. Each selector can be fi tted 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 fi bres 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 fi bres, the system doesn’t 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 fi bre 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.

MDT107 moduleThe MDT107 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.

Vacuum type switchgear Evolis 17.5 kV circuit breakerPresentation

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 fi eld 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 (IEC60056: class E2).

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

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

For the fi rst 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 benefi t 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 (IEC60056: 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.

Vacuum type switchgear Evolis 17.5 kV circuit breakerP2 stored energy operating mechanismRemote control

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).

Trip curvesThe trip curves for Fusarc CF (fi gure 1) and Ferraz (fi gure 2) fuses are shown above. These are the average curves with an rms current value tolerance I ± 10%.

Limitation curvesFusarc CF (fi gure 3) and Ferraz (fi gure 4) fuses have current limiting capacity. These curves give the maximum value of the limited breaking current Ic (in kA peak), as a function of the value Ip (in kA rms) of the presumed current that would be created if there were no protection. For further details, ask for the fuse catalogues.

Description of the deviceThe LF circuit breaker consists of:

the circuit breaker unit with its operating mechanism:3 poles integrated in a “sealed pressure system” type insulating enclosure.

The sealed assembly is fi lled with SF6 gas at low relative pressure (0.15 Mpa/1.5 bars) and equipped with a pressure switch

an RI stored energy electrical operating mechanism.This gives the device an opening and closing speed that is independent of the operator, for both electrical and manual orders. It enables reclosing cycles to be carried out

a front panel housing the manual operating mechanism and status indicators.the components enabling it to be withdrawable:the circuit breaker is equipped with racking arms and contact fi ngers and mounted

on a racking in/out drive device with a threaded shaft activated by a handle, including all of the safety interlock systems.

a Harting type male LV connector allows connection of the external auxiliary circuits.Each device can optionally be fi tted with:

locking of the circuit breaker in the following positions:open, by a key lock installed on the control panelracked out, by a key lock installed on the drive device.

Specifi c applicationsProtection of generators and power station auxiliariesAll circuit breakers in the LF range break short circuit currents with an asymmetry of at least 30%. In cases where the network constant X/R is greater than 45 ms, the asymmetry to be broken is higher; this is often the case of circuit breakers protecting nuclear or thermal power station auxiliaries or circuit breakers that are close to generator sets or large transformers. Specifi c tests have been carried out:Circuit breakers kV kA Asymmetry

12 40 50%17.5 25 100%

Switching and protection of capacitor banksLF range circuit breakers are particularly well suited to switching and protection of capacitor banks; they are classed C2 according to standard IEC 62271-100. Tests carried out according to the standard for breaking at 400 A with making and breaking cycles in case of a capacitor bank with a making current of 20 kA.Additional tests have been carried out: please consult us.

CompositionThe opening circuit can be produced using the following components:

shunt opening release (on energizing) (YO1)second shunt opening release (on energizing) (YO2)undervoltage release (YM)low energy release (Mitop).

Note: see the table of the releases’ combinations page 57.

V AC (60 Hz) 120, 240V DC 24, 30, 48, 60, 110, 125, 220



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

FunctionRemote control enables the remote opening and closing of the circuit breaker.

CompositionThe remote control mechanism comprises:

an electrical motor with gearing a shunt closing release (YF) combined with an anti-pumping devicean operation counter.

Electrical motor with gearing (M)The electrical motor arms and re-arms the stored energy unit as soon as the circuit breaker is closed. This allows the instant closing of the device after opening. The arming lever is only used as a back-up operating mechanism in the case of any auxiliary power supply. The M3 contact indicates the end of arming operations.

“Open/closed” auxiliary contacts The number of contacts available depends on the options chosen on the operating mechanism.In the basic confi guration, the circuit breaker’s operating mechanism comprises a total of:

5 normally closed contacts (NC)5 normally open contacts (NO)1 changeover contact (CHG).

The usage procedure for auxiliary contacts is given in the following table:

In order to know the fi nal number of available contacts, you must deduct the total number of contacts included in the circuit breaker (5 NC + 5 NO + 1 CHG), the number of contacts used given in the table above.E.g.: a circuit breaker equipped with a remote control and a shunt trip unit has the following available contacts: 5 NC + 4 NO + 1 CHG. With a undervoltage release instead of the shunt trip, this circuit breaker would have the following available contacts: 5 NC + 5 NO + 1 CHG.

222 Switch

The three rotating contacts are placed in an enclosure fi lled with gas to a relative pressure of 0.04 MPa (0.4 bars).The system offers maximum operating reliability.Gas tightnessThe SF6 fi lled enclosure is of the “sealed pressure system type”. Sealing tightness is always checked in the factory.Safety

The switch may be in one of three positions: “closed”, “open” or “earthed”, giving a natural interlocking system that prevents operator error.

Moving contact rotation is driven by a fast acting mechanism that is independent of the operator.

The device combines the breaking and disconnecting functions.The SF6-enclosed earthing switch has a short-circuit making capacity

in compliance with standards.Breaking principleThe outstanding qualities of SF6 gas are used to extinguish the electrical arc. To increase cooling of the arc, a relative movement is created between the arc and the gas. The arc strikes when the fi xed and moving contacts separate. The combination of the current and a magnetic fi eld created by a permanent magnet causes the arc to rotate around the fi xed contact, extending and cooling it until it is extinguished at current zero point. The distance between the fi xed and moving contacts is then suffi cient to withstand the recovery voltage.This system is both simple and dependable, and it provides improved electrical endurance due to very low wear of contacts.

SF6 type switchgear DI switch cubicleFuses

Fuse ratings for MCset protection units depend, among other things, on the following criteria:

service voltagetransformer ratingfuse technology (manufacturer).

Different types of fuses with medium loaded striker maybe installed: Solefuse: fuses as per standard UTE NCF 64.210Fusarc CF: fuses as per IEC recommendation 60.282.1 and DIN dimensions 43.625.

For fuse-switch combination unit, refer only to the selection table and reference list of fuses. For all other type of fuses, consult us.Example: for the protection of a 400 kVA transformer at 22 kV, select either Solefuse fuses rated 16 A or Fusarc CF fuses rated 25 A.

Fuse selection tableRating in A. No overload at –5°C < t < 40°C. Please consult us for overloads and operation over 40°C for France Transfo oil immersed type transformers.

901R Switchgear resistance to ageing in a substation depends on

3 key factorsThe need for correctly made connections

New cold connecting technologies offer easy installation and favour durability in time. Their design means they can be used in polluted environments with harsh atmospheres.

The impact of relative humidityThe installing of a heating element is essential in climates with high relative humidities and signifi cant temperature differentials.

Ventilation controlThe dimensions of air vents must be appropriate for the dissipated energy in the substation. They must only sweep across the transformer environment.Cold connected terminalsSchneider Electric’s experience has led it to favour this technology wherever possible for optimum durability. The maximum acceptable cable cross-section for standard assemblies are:

630 mm2 for incomer or feeder cubicles with single-pole cables,400 mm2 for incomer or feeder cubicles with three-pole cables,95 mm2 for transformer protection cubicles with fuses.

Access to the compartment is only possible when the earthing switch is closed.Tightening torques for cables will be attained using a dynamo wrench set to 50 mN.
