Quality - Environment Maintenance
Presentation
Certified quality: ISO 9001 and ISO 9002
In 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:
b uniform throughout all departments,
b recognized by many customers and approved organizations.
MT55055
MT55054
A major asset
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 checks
DE57460
Copper

Plastic
Steel
During manufacture, each MCset functional unit is subject to systematic
routine testing with the aim of checking the quality and conformity
of the following features:
b measuring of opening and closing speeds,
b measuring of operating torque,
b dielectric test,
b testing of safety systems and interlocks,
b testing of low voltage components,
b conformity with drawings and diagrams.
The results obtained are recorded and approved by the quality control
department on each device’s test certificate.
This therefore guarantees product traceability.
b Checking SF6 switchgear
v sealing test,
v filling pressure test.
b 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.

Description (cont.)
Make up of an MCset switchboard
MCset 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 unit
A 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 fulfil this function:
b the cubicle,
b the protection, monitoring and control system,
b the withdrawable part.
LSC2B
(Loss of Service Continuity IEC 62271-200):
this category defines the possibility
of keeping other compartments energised
(in service) when opening a main circuit
compartment.
The cubicle
The cubicle is of LSC2B (Loss of Service Continuity Category) type as defined 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:
b the busbars,
b the withdrawable part (circuit-breaker, fuse-contactor, disconnector truck or
earthing truck),
b 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.
Five basic cubicle layouts are offered:
b incomer or feeder
AD
b line up bussection
CL - GL
b busbar metering and earthing
TT
b switch-fuse feeder
DI
AD and CL cubicles have withdrawable vacuum type circuit-breaker and
contactor switchgear.
The protection, monitoring and control system
This includes:
b Sepam, protection, monitoring and control unit,
b current sensors, which may be of 3 types,
v conventional current transformers,
v low voltage toroid type current transformers,
v LPCT type current transformers.
v CSP type broad-range current transformers,
b voltage transformers,
b zero sequence core balance current transformers (CSH type).
The withdrawable part
This includes:
b the circuit-breaker, contactor or the earthing truck with its closing and opening
mechanism, or the disconnector truck,
b the lever-type propulsion mechanism for racking in-out,
b interlocks to fix the withdrawable part on the fixed part either in service position
or disconnected.

Protection of people
MT20076
MCset internal arc
Basic version (gas exhaust)
MCset is designed to eliminate the effects of internal arcing in total safety, due to:
b metal flaps positioned above the enclosure, which in the case of internal fault,
limit overpressure in the compartments.
b nonflammable materials used for the cubicle.
MCset switchboard with tunnel
Internal arc version
MCset 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.
b 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.
b 4-sided internal arc protection
In 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.
b Installation in a room with limited ceiling height:
v height exceeding 2.8 m, potential for installing a tunnel above the switchboard to
prevent reflection of hot gases on the ceiling.
Ceiling height
2.8 m < h < 4 m
h>4m
Tunnel
Mandatory
Not mandatory
b 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.
v electromechanical detector
This system employs a positive security electromechanical tripping circuit,
positioned on the cubicle’s flap valves.
This set transmits the information to the Sepam to give the opening order to the
circuit breaker located upstream of the fault.
v 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.
MT20077
Dependable mechanical control devices
All 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:
b racking in and out is only possible with the door closed.
b locking of the MV door open if the LV plug of the circuit breaker is not plug-in.
b 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.
b all operations are carried out from the front face including access to connections
and busbars.
b the voltage present indicator is located on the front face of the functional unit,
in the immediate vicinity of the earthing switch control.
b disarming of circuit breaker when racking out. This function enables the circuit
breaker control springs to be disarmed during the extraction operation.
b 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.

b Internal arcing withstand is ensured by the use of a tunnel specifically designed
for marine applications. Located above the cubicle, it can evacuate gases due to
arcing effects.
b A low voltage control cabinet has also been designed to meet the need for using
numerous control and monitoring systems and LV components.
b The cubicles are provided with switchgear employing SF6 or vacuum technology
(please consult us).
b The incoming/outgoing feeder cubicles are connected by cables through the bottom.
b Skids are available on option to group together several cubicles on a platform
for improved rigidity and to absorb vibrations by means of dampers.
They also facilitate handling and installation of the switchboard.
b Motor starter applications: see Motorpact catalogue.

Thermal diagnosis
Continuity of service is of prime importance
for electrical power supplies, particularly.
for heavy industries.
By using the new thermal diagnosis system
developed for MCset, we offer you
the possibility of monitoring on an on-going
basis, thus reducing the probability of failure
and reducing maintenance time.
Thermal diagnosis system
DE56780
Protection, monitoring
and control
Use
To 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.
Presentation
Thermal diagnosis is based on the principle of temperature measurement
of energized circuits. By using optical fibres, the system doesn’t introduce any risks
in terms of insulation.
It provides:
b permanent monitoring of the temperature rise in power circuits at the connections,
b tripping of a “pre-alarm”, then an “alarm” by activating dry contact outputs,
b indication of the zone and circuit involved.
The standard solution is composed of the MDT module and two probes
as described hereunder.
Probes CFO733
The optical fibre probes are factory-built assemblies comprising:
b 3 sensors attached to the power circuit,
b the optical connections,
b a connector linked to the module.
This connector incorporates the opto-electrical conversion unit thus eliminating
any optical connections when assembling.
MDT106 module
The MDT106 electronic module is mounted in the low voltage compartment
of the cubicle. It provides the following functions:
b monitoring of temperature rise in 2 zones,
b triggering of the pre-alarm,
b triggering of the alarm,
b self-monitoring of the module,
b self monitoring of the temperature probes.

Conventional current transformers
Conventional current transformers are used to provide power to metering,
measuring or control devices. They measure the value of primary current
from 10 A to 3150 A.
Schneider Electric has drawn up a list of current transformers which are appropriate
for use with digital protection devices in order to make it easier to determine
accuracy characteristics. This list is available in the selection guide on page 81.

Voltage transformers
These supply power to:
b measuring, metering and monitoring devices,
b relays or protective devices,
b auxiliary LV sources for various types of switchgear; all these devices are protected
and insulated from the MV section.
They are installed at the bottom of the functional unit. In the withdrawable fuse
version, the voltage transformers are attached to a side wall. The energized part
is entirely encapsulated in an epoxy resin, which provides both electrical insulation
and excellent mechanical strength.
They include the following models:
b with one insulated MV terminal, for connection between neutral and phase
conductors in three-phase systems with withdrawable MV fuses,
b with two insulated MV terminals, for connection between phase conductors.

Evolis 17.5 kV circuit breaker
Presentation
PE56565
Presentation
The 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 endurance
A 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:
b a very compact interrupter unit,
b 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 endurance
This magnetic field is generated by a patented outside coil which surrounds
the contact area. This solution has many advantages:
b a simplified and therefore reliable interrupter unit,
b 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).

PE56600
Operation of the P2 stored energy operating mechanism
This mechanism guarantees the device an opening and closing speed unaffected
by the operator, for both electric and manual orders.
It carries out the O and CO cycles and is automatically recharged
by a gear motor after closing.
It consists of:
b the stored energy operating mechanism which stores in springs the energy
required to open and close the device
b a gear motor electrical charging device with manual charging by lever
(useful on loss of auxiliary supply)
b manual order devices by push buttons on the front panel of the device
b an electrical remote closing device containing a release with an antipumping relay
b an electrical opening device containing one or more releases, for example:
v shunt opening
v Undervoltage
v Mitop, a low consumption release, used only with the Sepam 100 LA
protection relay.
b an operation counter
b a position indication device by mechanical indicator
and 3 modules of 4 auxiliary contacts whose availability varies according
to the diagram used
b a device for indicating “charged” operating mechanism status by mechanical
indicator and electrical contact.

Undervoltage release (MN)
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 possible when
the supply voltage of the release unit reaches 85% of its rated voltage.

Time delay for MN
DE57529
To 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.

Evolis 17.5 kV circuit breaker
P2 stored energy operating mechanism
Remote control
DE57530
Function
Remote 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 antipumping 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.
Composition
Circuit breaker equipped with remote control
The remote control comprises:
b an electrical motor (MCH) equipped with a “spring armed” CH limit switch
b a shunt closing release (XF).
DE57531
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.

LF circuit breaker
Presentation
PE56566
Description of the device
The LF circuit breaker consists of:
b the circuit breaker unit with its operating mechanism:
v 3 poles integrated in a “sealed pressure system” type insulating enclosure.
The sealed assembly is filled with SF6 gas at low relative pressure
(0.15 Mpa/1.5 bars) and equipped with a pressure switch
v 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
v a front panel housing the manual operating mechanism and status indicators.
b the components enabling it to be withdrawable:
v the circuit breaker is equipped with racking arms and contact fingers and mounted
on a racking in/out drive device with a threaded shaft activated by a handle,
including all of the safety interlock systems.
v a Harting type male LV connector allows connection of the external auxiliary circuits.
Each device can optionally be fitted with:
b locking of the circuit breaker in the following positions:
v open, by a key lock installed on the control panel
v racked out, by a key lock installed on the drive device.
Specific applications
Protection of generators and power station auxiliaries
All 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.

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.

RI stored energy operating mechanism
Presentation
PE57164
Operation of the RI stored energy operating mechanism
This gives the device an opening and closing speed that is independent of the
operator whether the order is electrical or manual.
The electrical control mechanism carries out reclosing cycles and is automatically
recharged by a geared motor each time after closing.
It consists of:
b the stored energy operating mechanism which stores in springs the energy
required to open and close the device
b a manual lever-operated spring arming device
b a geared electrical arming device which automatically re-arms the control
mechanism as soon as the circuit breaker is closed (optional)
b manual order devices by push buttons on the front panel of the device
b an electrical remote closing device containing a release with an antipumping relay
b an electrical opening order device comprising one or several release units which
can be of the following type:
v shunt opening
v undervoltage
v Mitop, a low consumption release, used only with the Sepam 100 LA
protection relay.
b an operation counter
b an “open/closed” position indicator device with a mechanical indicator
b a device for indicating “charged” operating mechanism status by mechanical
indicator and electrical contact (optional)
b a module of 14 auxiliary contacts whose availability varies according
to the diagram used
b a single contact pressure switch is activated when the gas pressure exceeds
0.1 MPa (relative pressure: 1 bar).

Function
Remote control enables the remote opening and closing of the circuit breaker.
Composition
The remote control mechanism comprises:
b an electrical motor with gearing
b a shunt closing release (YF) combined with an anti-pumping device
b an operation counter.
Electrical motor with gearing (M)
The electrical motor carries out the automatic rearming of the stored energy unit as
soon as the circuit breaker is closed. This allows the instant reclosing of the device
after opening. The arming lever is only used as a backup operating mechanism
in the case of the absence of the auxiliary power supply.
The M3 contact indicates the end of arming operations.

Switch
The three rotating contacts are placed in an enclosure filled with gas to a relative
pressure of 0.04 MPa (0.4 bars).
The system offers maximum operating reliability.
Gas tightness
The SF6 filled enclosure is of the “sealed pressure system type”. Sealing tightness
is always checked in the factory.
Safety
b The switch may be in one of three positions: “closed”, “open” or “earthed”,
giving a natural interlocking system that prevents operator error.
b Moving contact rotation is driven by a fast acting mechanism that is independent
of the operator.
b The device combines the breaking and disconnecting functions.
b The SF6-enclosed earthing switch has a short-circuit making capacity
in compliance with standards.
DE57486
Breaking principle
The 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 fixed and moving contacts separate.
The combination of the current and a magnetic field created by a permanent magnet
causes the arc to rotate around the fixed contact, extending and cooling it until
it is extinguished at current zero point. The distance between the fixed and moving
contacts is then sufficient 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.

b Switch function:
v independent closing in two steps:
- operating mechanism recharged by a hand lever or motor,
- stored energy released by a push button (I) or trip unit,
v independent opening by push button (O) or trip unit.
b Earthing switch function:
v independent closing by a hand lever.
Operating energy is provided by the compression of a spring which causes
the contacts to close or open after the neutral point is passed.
b Auxiliary contacts:
v switch (2 O + 2 C),
v switch (2 O + 3 C) and earthing switch (1 O + 1 C),

Fuses
Fuse ratings for MCset protection units depend, among other things,
on the following criteria:
b service voltage
b transformer rating
b fuse technology (manufacturer).
Different types of fuses with medium loaded striker maybe installed:
b Solefuse: fuses as per standard UTE NCF 64.210
b Fusarc 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 10 kV, select either Solefuse
fuses rated 43 A or Fusarc CF fuses rated 50 A.
Fuse selection table
Rating in A. No overload at –5°C < t < 40°C.
Please consult us for overloads and operation over 40°C for France Transfo

Switchgear resistance to ageing in a substation depends on
3 key factors
b The 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.
b The impact of relative humidity
The installing of a heating element is essential in climates with high relative
humidities and significant temperature differentials.
b Ventilation control
The dimensions of air vents must be appropriate for the dissipated energy
in the substation. They must only sweep across the transformer environment.
Cold connected terminals
Schneider 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:
b 630 mm2 for incomer or feeder cubicles with single-pole cables,
b 400 mm2 for incomer or feeder cubicles with three-pole cables,
b 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.
