General
A major asset
In each of its business units or manufacturing plants, Schneider Electric integrates
a functional organisation whose main role is to check quality and monitor
compliance with standards.
This procedure is:
■ Uniform throughout all departments
■ Recognised by many customers and approved organisations
But above all, its strict application has allowed us to obtain the recognition of
an independent organisation as example: The French Quality Assurance
Association (AFAQ).
The quality system for the design and manufacture is certified to be in
conformity with the requirements of the ISO 9001: 2008 quality assurance
standard.
Strict and systematic checks
During manufacture, each functional unit is subject to systematic, routine testing
with the aim of checking the quality and conformity of the following features:
■ Measurement of the opening and closing speeds
■ Measurement of the operating torque
■ Dielectric test
■ Testing of the safety systems and interlocks
■ Testing of the low voltage components
■ Conformity with drawings and diagrams
The results obtained are recorded and approved by the quality control department
on the test report of each device.
This, therefore, guarantees product traceability.
■ Checking SF6 Circuit Breaker
□ sealing test
□ filling pressure test
Protected environment
Schneider Electric is committed to a long-term environmental approach.
All necessary measures have been taken in conjunction with our services,
suppliers and subcontractors to ensure that the materials used in the composition
of the equipment do not contain any substances prohibited by regulations and
directives.
In order to help you protect the environment and 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.
Our Air Insulated Switchgear is 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 equipment’s life and reused after
treatment
■ The environmental management system adopted by Schneider Electric’s production
sites for the manufacture of our Air Insulated Switchgear has been assessed and
recognised as conforming to the requirements of the ISO 14001 standard

For over sixty years, Schneider Electric, leverages its experience to develop vacuum and SF6 circuit breakers
and thus holds a unique know-how in various applications of these techniques cut.
Schneider Electric, from the beginning at the outposts of these two complementary technologies, has
allowed Research & Development teams, to bring them to their maximum performance.
Thus, based on our long market experience, we can, better than anyone, help objectively and effectively in
the selection of the apparatus according to your habits, applications or specific requirements.
SF6
The dielectric rigidity and
the remarkable cut-off
characteristics of this gas,
put a high value on the SF6
devices worldwide since the
middle of the 1950s.
Since then, the progress realized
in term of waterproofness and
SF6 end of life processing,
have again reinforced
their credibility.

Vacuum
From the beginning of the last
century, the interruption of current
in the vacuum was regarded as
an "ideal" technical cut-off.
Nevertheless, several technical
difficulties relegated the vacuum
technique in the background for
nearly three decades, until that
numerous innovations from
the beginning of the 1960s, gave
it its "letters patent of nobility".

MCset switchgear SF6 circuit breaker
MCset switchboards
are made up of several
interconnected functional
units.
The power connections
are made between the
functional units within a
switchboard via a single
busbar.
The electrical continuity
of all of the 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.
Low voltage cables can
enter the switchboard
through the top or bottom
of each functional unit.
Description of a functional unit
A functional unit consists of all of the equipment in the main and auxiliary circuits which together provide a
protection function. Each functional unit combines all of the components which are required to fulfil this function:
■■ The cubicle, and
■■ The protection, monitoring and control system (including the withdrawable live part).
Accessibility of the MV compartments
The withdrawable part
Interlock-controlled accessible compartment:
■■ Withdrawable MV part (circuit breaker, contactor)
compartment for AD/RHC/RHB/CL units.
The withdrawable function gives the ability
to disconnect devices.
It includes:
■■ The circuit breaker, contactor, or the earthing truck,
■■ The propulsion mechanism for racking in and racking
out, and
■■ Interlocks to fix the withdrawable part, either in
a service or disconnecting position
Tool-based accessible compartments:
■■ Cable compartment, main busbar for
the AD/RHC/ CL/GL/DI units
■■ Busbar compartment for the RHB
■■ Bottom busbar compartment for the CL/GL units
■■ Fixed bridge compartment for the GL unit
The protection, monitoring
and control system
This includes:
■■ The Sepam, MiCOM, protection, monitoring and
control unit
■■ The GemControl monitoring and control unit
■■ The Vamp arc flash protection system
■■ Current sensors, which may be of 4 types,
□□ a conventional current transformer Current
Transformer
□□ toroid type Current Transformers
□□ LPCT type Current Transformers
□□ CSP type broad-range Current Transformers
(for MCset 17.5 kV)
■■ Voltage Transformers, and
■■ Zero sequence core balance Current Transformers

The cubicle
LSC2B
(Loss of Service
Continuity IEC 62271200):
this category defines
the possibility of
keeping other
compartments
energised (in service)
when opening a main
circuit compartment.
The cubicle is a LSC2B (Loss of Service Continuity
Category) type as defined by IEC standard 62271200; in other words, the medium voltage parts are
compartmented using metal partitions (PM class)
that are connected to earth and which separate:
■■ The busbars
■■ The withdrawable part (circuit-breaker, fusecontactor, disconnector truck or earthing truck), and
■■ The MV connections, earthing switch, current
sensors and Voltage Transformers, as required
MCset guarantees a high level of protection of people;
when an accessible compartment is open, the other
compartments and/or functional units may remain
energised.
The low voltage auxiliaries and monitoring unit are in
a control cabinet separate from the medium voltage
section.
Five basic cubicle layouts are offered:
■■ Incomer or feeder
AD
■■ Direct Incomer RD (for 24 kV)
■■ Line-up bussection
CL - GL
■■ Busbar metering and earthing
TT
■■ Fuse-switch feeder

DI cubicles including a switch-fuse are used to supply power and protect low power transformers.
E.g.: auxiliary service transformers in primary substations.
All functional interlocks meet recommendations in IEC 62271-200:
■■ The switch is only possible to close if the earthing switch is open and the connection access panel is in place
■■ Closing of the earthing switch is only possible if the switch is open
■■ Opening of the access panel to medium voltage connections and fuses is only possible when the earthing switches
upstream and downstream of the fuses are closed
■■ The switch is locked in the open position when the access panel is taken off
The voltage presence indicator is situated on the front face of the functional unit, integrated in the switch’s
control panel.

Description of the device
The 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 filled 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 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
□□ A Harting type male LV connector allows connection of the external auxiliary circuits
Each device can optionally be fitted with:
■■ Locking of the circuit breaker in the following positions:
□□ Open, by a key lock installed on the control panel
□□ 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 are carried out according to the standard for breaking at 400 A with making
and breaking cycles in the case of a capacitor bank with a making current of 20 kA.

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 performs the reclosing cycles and is automatically
recharged by a geared motor each time after closing.
It consists of:
■■ A stored energy operating mechanism which stores the energy required to open
and close the device in the springs
■■ A manual lever-operated spring arming device
■■ A geared electrical arming device which automatically re-arms the control
mechanism as soon as the circuit breaker is closed (optional)
■■ Push button manual order devices on the front panel of the device
■■ An electrical remote closing device containing a release with an antipumping relay
■■ An electrical opening order device consisting of one or several release units
which can be of the following type:
□□ shunt opening
□□ undervoltage
□□ Mitop, a low consumption release, used only with the Sepam 100 LA
protection relay.
■■ An operation counter
■■ An “open/closed” position indicator device with a mechanical indicator
■■ A device to indictate the "charged" operating mechanism status via mechanical
indicator and electrical contact (optional)
■■ A module of 14 auxiliary contacts whose availability varies according
to the diagram used
■■ A single contact pressure switch is activated when the gas pressure exceeds
0.1 MPa (relative pressure: 1 bar)

In the basic configuration, the circuit breaker’s operating mechanism mechanism
consists of a total of:
■■ 5 normally closed contacts (NC)
■■ 5 normally open contacts (NO)
■■ 1 changeover contact (CHG)

Presentation - Characteristics
PE56744
SF range circuit breakers equip cubicles AD4 and CL4
for rated voltage values of 24 kV.
They work on the basis of the “puffer” type principle in SF6, which is used as
a breaking and insulating medium.
Each of the 3 poles has an independent insulating enclosure which forms a filled
pressure system in compliance with IEC standard 62271-100.
Each pole forms a gas-tight unit filled with low pressure SF6 at a low relative pressure
of 0.05 to 0.35 MPa (0.5 to 3.5 bars) according to the performance level required.
No filling is required during the life of the equipment.
According to the performance levels, it is possible as an option to equip SF6 circuit
breakers with a pressure switch to act on an alarm in the case of a pressure drop.
SF6 range circuit breakers are actuated by a GMH type spring mechanism.
Principle of the puffer breaking technique
The main contacts and arcing contacts are initially closed (Fig. 1).
Pre-compression (Fig. 2)
When the contacts begin to open, the piston slightly compresses the SF6 gas
in the pressure chamber.
Arcing period (Fig. 3)
The arc appears between the arcing contacts. The piston continues its downward
movement. A small quantity of gas, directed by the insulating nozzle, is injected
across the arc. For the breaking of low currents, the arc is cooled by forced
convection. However, for high currents, thermal expansion causes the hot gases to
move towards the cooler parts of the pole unit.
The distance between the two arcing contacts becomes sufficient for the current to
be broken when it reaches the zero point due to the dielectric properties of the SF6.
DE53514
Sweeping overstroke (Fig. 4)
The moving parts finish their movement and the injection of cold gas continues until
the contacts are completely open.

■ A manual spring charging system
■ An electrical motor spring charging device that automatically recharges
the mechanism as soon as the contacts close (recharging time < 15 s)
■ Two mechanical push ■uttons for opening and closing, accessi■le with
the cu■icle door open (circuit ■reaker in test position)
■ An electrical closing system containing a closing release for remote control
and an anti-pumping relay
■ An electrical opening system containing one or more opening releases
of the following type:
□ shunt
□ undervoltage.
■ An operation counter
■ An optional “operating mechanism charged” indication contact
■ An end-of-charging contact
■ A ■lack-white mechanical “open-closed” position indicator
■ A multi-pin connector to isolate auxiliary circuits in the “racked out” position
Auxiliary contacts
The GMH operating mechanism is equipped with a ■lock of 14 auxiliary contacts
including:

Temporary service or periodic service
The two curve systems (Fig. 1 and 2) can be used to determine the maximum current surges accepted by the Rollarc 400 contactor,
in temporary or periodic service.
■■ Temporary service: knowing the steady state current Ip, we can determine the maximum duration Ts of a current surge Is from graph 1 (Fig. 2).
■■ Periodic service: knowing 3 of the following 4 parameters:
□□ overcurrent Is
□□ overcurrent time Ts
□□ cooling current Ir
□□ cooling time Tr.
We can determine the 4th parameter using graph 2 (Fig. 1 and 2).

The fuses used are the FUSARC CF or FERRAZ type (Standard IEC 60282.1
and DIN 43625) with high breaking capacity.
Substantial fault current limitation reduces the electrodynamic stresses
on the load-side components (contactor, cables, CT, etc).
A “blown fuse” device is used to open the three poles of the contactor.

The trip curves for FUSARC CF (Fig. 1) and FERRAZ (Fig. 2) fuses are shown
opposite.
These are the average curves with an rms current value tolerance ± 10%.
Limitation curves
FUSARC CF (Fig. 3) and FERRAZ (Fig. 4) fuses have current limiting capacity.
These curves give the maximum value of the limited breaking current Ic (in kA

Loadbreak switch
The three rotating contacts are placed in an enclosure filled with gas at a relative
pressure of 0.04 MPa (0.4 bars).
The system offers maximum operating reliability.
Gas tightness
The SF6 filled enclosur is a "sealed pressure system" type. Sealing tightness
is always checked at the factory.
Safety
■■ The switch may be in one of three positions: “closed”, “open” or “earthed”,
creating 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 the relevant standards
Insensitivity to the environment
■■ Parts are designed in order to obtain optimum electrical field distribution
■■ The metallic structure of cubicles is designed to withstand and aggressive
environment and make it impossible to access any energised part during
operation
DE57486v
Breaking principle
The outstanding qualities of SF6 gas are used to extinguish the electrical arc.
To increase the 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 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 provides improved electrical
endurance due to the very low wear of contacts.

Operating mechanism and auxiliaries
CI2 double function operating mechanism
■■ Switch function:
□□ 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
□□ independent opening by push button (O) or trip unit
■■ Earthing switch function:
□□ 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.
■■ Auxiliary contacts:
□□ switch (2 O + 2 C)
□□ switch (2 O + 3 C) and earthing switch (1 O + 1 C)
□□ switch (1 C) and earthing switch (1 O + 1 C) in the motor option
■■ Motor option
■■ Opening release:
□□ shunt
□□ undervoltage (optional)
■■ Closing release: shunt trip
■■ Fuse blown release: any fuse blown trips the opening of the switch

Fuses
Fuse ratings for MCset protection units depend, among other things,
on the following criteria:
■■ Service voltage
■■ Transformer rating
■■ Fuse technology (manufacturer)
Different types of fuses with a medium loaded striker may be installed:
■■ Solefuse: fuses as per standard UTE NCF 64.210
■■ Fusarc CF: fuses as per IEC recommendation 60.282.1 and DIN dimensions 43.625
For a 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

Switchgear resistance to ageing in a substation depends on
3 key factors
■■ The need for correctly performed 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 humidity
The installation of a heating element is essential in climates with high relative
humidities and significant temperature differentials.
■■ 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:
■■ 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.
The cable torques is to be done using a dynamo wrench set to 50 mN.

PIX switchboards are
made up of several
interconnected functional
units.
Power connections
are made between the
functional units within
a switchboard via
a single busbar.
The electrical continuity
of all of the 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.
LSC2B
(Loss of Service
Continuity IEC 62271200):
this category defines
the possibility of
keeping other
compartments
energised (in service)
when opening a main
circuit compartment.
Description of a functional unit
A functional unit consists of all of the equipment in the main and auxiliary circuits which together provide a
protection function. Each functional unit combines all of the components which are required to fulfil this function:
■■ The cubicle, and
■■ The protection, monitoring and control system (including the withdrawable live part)
Accessibility of the MV compartments
The withdrawable part
Interlock-controlled accessible compartment:
■■ Withdrawable MV part (circuit breaker, contactor)
compartment
The withdrawable function gives the ability
to disconnect devices.
It includes:
■■ The circuit breaker, contactor, or the earthing truck
■■ The propulsion mechanism for racking in and racking
out, and
■■ Interlocks to fix the withdrawable part either in
a service or disconnecting position
Tool-based accessible compartments:
■■ Cable compartment
■■ Busbar compartment
■■ Fixed parts compartment
The protection, monitoring
and control system
This includes:
■■ The Sepam, MiCOM, protection, monitoring and
control unit
■■ The GemControl monitoring and control unit
■■ The Vamp arc flash protection system
■■ Current sensors, which may be of 3 types,
□□ a conventional Current Transformer
□□ toroid type Current Transformers
□□ LPCT type Current Transformers
■■ Voltage Transformers, and
■■ Zero sequence core balance Current Transformers
(CSH type).

The cubicle
The cubicle is a LSC2B (Loss of Service Continuity
Category) type as defined by IEC standard 62271200; 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, fusecontactor, disconnector truck or earthing truck), and
■■ The MV connections, earthing switch, current
sensors and Voltage Transformers, as required
PIX guarantees a high level of protection of people;
when a compartmen 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
CB
■■ Fuse-switch feeder
T1
■■ Line-up bussection

HVX circuit breaker
Presentation - Characteristics
PE58245
Description of the device
HVX is our latest range of vacuum circuit breakers. It offers a proven state-of-theart design to meet your specifications for power switching devices in air-insulated
switchgear up to 36 kV. HVX brings a valuable solution to your project.
Thanks to its improved contact design, our interrupters provide unrivalled
performance for their reduced size.
Operating mechanisms have been simplified to increase reliability and give
extended life with very low maintenance. Instead of the traditional spring operating
mechanism, HVX implemented a singleshaft system with only one torsion spring,
reducing the number of parts and increasing the reliability.
Application
HVX is designed to suit all types of applications (utilities, power generation,
O&G, industry, etc.) and for breaking short-circuit as well as transformers
(under load and no-load conditions), generators, capacitor banks and motors.
HVX up to 2000 A
PE58246
Flexibility
HVX is available in a range of standard, fixed or withdrawable configurations,
with plug-in (finger or tulip type) or bolted connections.
HVX can be integrated in our medium voltage switchboard PIX or can be offered
with a pre-engineered power module which incorporates a chassis with metal
shutters, earthing switch, mechanical interlocks, multi-functional bushings
and various electrical options to facilitate switchboard integration.
Standard
HVX has been fully tested according to IEC 62271-100 at 50 Hz and 60 Hz
and the latest GOST standards. The highest level of the above mentioned
standards has been passed including M2, E2, C2.
HVX has also been certified to ANSI C37.013 for generator circuit breaker
applications up to 25 kA.

Protection, monitoring and
control
The arc protection unit detects an arc flash in
an installation and trips the feeding breaker.
An arc flash protection system maximises
personnel safety and minimises
material damage caused by arc faults.
Arc flash protection maximises personnel safety and minimises material damage
to the installation in the most hazardous power system fault situations.
Minimised damage also means a limited need for repair work and enables rapid
restoration of the power supply.

Vamp advantages
Personnel Safety
A fast and reliable arc protection unit may save human lives in the event of an arc
fault occuring in the switchgear during work in or near an installation.
Reduces production losses
The shorter the operating time of the arc flash protection unit, the smaller will be
the damage caused by the arc fault and the shorter the possible power outage.
Extended switchgear life cycle
A modern arc protection unit increases the life-cycle expectancy of switchgear
installations, so that decisions to invest in new switchgear installations can be
postponed and money can be saved by re-Vamping existing switchgear systems.
Reduced insurance costs
The faster and better the protection system of a power installation, the more
generous will be the terms and costs of insurance.
Vamp 221
PE58215
Low investment costs and fast installation
A comprehensive arc protection system is characterised by low investment costs
and fast installation and commissioning times. One successful operation of the arc
flash protection units provides an immediate investment payoff.
Reliable operation
Operation is based on the appearance of light or alternatively on the appearance of
light and current from an external device. Immune to nuisance trippings due to dual
tripping criteria: light and current.

which, in the case of an internal fault, limit
overpressure in the compartments.
■ Nonflammable materials used for the cubicle.
Our Air Insulated Switchgear is designed to withstand and protect operators
in the case of failure due to an internal arc.
Our Air Insulated Switchgear have been successfully type tested.
Protection against internal arcing is available on devices with 25 kA, 31.5 kA,
40 kA and 50 kA ratings.
Our Air Insulated Switchgear provides several options to install an internal
arc switchboard.
■ 3-sided internal arc protection
For a 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 protection
In the case of a 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.
■ Internal arcing detector (option)
Our Air Insulated Switchgear has 2 systems that can detect internal arcing
and switch off the power supply to limit the fault duration.
□ Electromagnetic detector
This system employs a positive security electromechanical tripping circuit,
positioned on the cubicle’s flaps (only MCset).
This set transmits the information to the Sepam to give the opening order to the
circuit breaker located upstream of the fault.
□ Vamp arc flash protection
The arc protection unit detects an arc flash in an installation and trips
the feeding breaker. Arc flash protection improves personnel safety
and minimises material damage to the installation in the most hazardous
power system fault situations.

Protection, monitoring and

DE59563
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 ongoing basis,
thus reducing the probability of failure
and reducing maintenance time.
Thermal diagnosis
for MCset 17.5 kV
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 sensitive
connections (for example, cable connections and on top of MV fuse holders).
Presentation
Thermal diagnosis is based on the principle of temperature measurement
of energised circuits. By using optical fibres, the system does not 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 CFO733
The optical fibre probes are factory-built assemblies consisting of:
■ 3 sensors attached to the power circuit,
■ Optical connections, and
■ A connector linked to the module
This connector incorporates the opto-electrical conversion unit thus eliminating
any optical connections when assembling.
MDT106 module and MDT107 for Motorpact
The MDT electronic module is mounted in the low voltage compartment
of the cubicle. It provides the following functions:
■ Monitoring of temperature rise in maximum 3 zones
■ Triggering of the pre-alarm
■ Triggering of the alarm
■ Self-monitoring of the module
■ Self monitoring of the temperature probes

What is ProDiag Breaker?
ProDiag Breaker is a Schneider Electric diagnosis tool.
ProDiag Breaker compares the mechanical and electrical parameters measured
during the full operation of circuit breakers with the data collected from our
production facilities. This allows detecting possible failure in advance. It measures,
records and displays on a screen the key electrical parameters in MV and LV circuit
breakers, relating to opening, closing and springloading operations.
All this data is automatically compared with the criteria for the circuit breaker
designated in the software, which indicates which values are within the acceptable
range, which are on the limit and which are outside it.
Two tests are always performed on each circuit breakers, one at minimum voltage
and one at nominal voltage. A written report is generated and provided by Schneider
Electric so that the customer can use it as a tool to define the necessary corrective
action (maintenance, repair or replacement).
ProDiag Breaker is part is part of ProDiag preventive maintenance plan
Evaluation of circuit breakers using ProDiag Breaker includes:
■ Evaluation of the operating mechanism.
■ Measurement and comparison of the actual
contact resistance with that specifi ed by the manufacturer.
■ Measurement and comparison of the insulation resistance.
■ Evaluation of the general circuit breaker conditions based on the captured data.
ProDiag Breaker Objectives
Your priority is to enhance the reliability of
your installation:
■■ to ensure its continuity of service,
■■ to minimize the time for maintenance
& repair
■■ to perform maintenance
Only on the equipment requiring it
and only when necessary(conditional
preventive maintenance)
Moreover, analysis of the ProDiag Breaker time/ travel curve combined with the
current curve of the coil and phase contact detects possible faults, such as:
• Worn out latches and operating mechanisms.
• Faulty coils.
• Mechanical wear and tear and hardening of lubricating grease.
• Defective shock absorbers.
• Defective simultaneous contact operation (opening/closing).
Some maintenance programmes involve dismantling the circuit breaker mechanism
to check its condition. ProDiag Breaker using signals captured from the circuit
breaker operation, reduces maintenance costs compared with programs which
check the circuit breakers manually.
Where can ProDiag Breaker reduce costs?
■■ ProDiag Breaker significantly reduces the time taken to identify potential faults in a circuit
breaker, using operational analysis rather than inspection and mechanical re-sets.
■■ The software analyses the captured data and identifi es the specifi c problem area.
■■ A device’s normal operating life is increased by timely diagnostics of when and what
repairs are necessary.
■■ The tool comprises both hardware and software, resulting in a highly efficient predictive
maintenance program.
Results
ProDiag Breaker provides a report of the complete nature of the circuit breaker,
detailing: closing / opening time, contact simultaneity, bounce and resistance,
mechanical closing and opening forces.
This report enables any required maintenance to be targeted and time in order to
optimize the customer’s maintenance plan.

Diagnostics of partial discharges
What is ProDiag Corona?
ProDiag Corona is a Schneider Electric diagnosis tool.
ProDiag Corona detects partial discharges in Medium Voltage cubicles.
■■ Partial Discharge occurs across part of the insulation between two conducting
electrodes, without completely bridging the gap.
■■ Partial discharge can happen under normal working conditions as a result of
insulation breakdown due to premature aging caused by thermal or electrical
over-stressing of the high voltage system.
ProDiag Corona analyses the primary electrical signal through VIS (Voltage Indicator
System) fixed on the switchboards. Measurements are taken by
an electronic sensor and the data is transmitted to the ProDiag Corona software in
order to evaluate the level of criticality of the controlled equipment.
A written report is generated, which will be handed over by Schneider Electric so that
the customer can use it as a tool to define the necessary corrective action, whether
maintenance, repair or replacement.
ProDiag Corona is not a certification tool.
ProDiag Corona executes the assessment of the energized equipment, without any
shutdown and then without disruption for the users.
This system allows you to control all types of the most common partial discharges:
■■ Internal partial discharges
■■ Surface partial discharge
■■ Corona effect
ProDiag Corona diagnostic can be realized on most Medium Voltage equipment on
the market equipped with VIS.
Where can ProDiag Corona reduce costs?

ProDiag Corona significantly reduces the time taken to identify potential faults in a
switch, without electrical shutdown.
A device’s normal operating life is increased by timely diagnostics of when and what
repairs are necessary. ProDiag Corona is a trouble shooting anticipation tool which
can avoid internal arc risks and untimely tripping.
■■ The tool comprises both hardware and software, resulting in a highly efficient
preventive maintenance program.
Results
ProDiag Corona provides a report of the complete electrical room , detailing :
ventilation, air filtration, due point calculation, level of criticability of each set of
equipment, constructor recommendations on any potential maintenance, repair &
rehabilitation.
This report enables any required maintenance to be targeted and timed to optimize
the customer’s maintenance plan.
ProDiag Corona is performed thanks to XDP2 testing equipment from NDB
