Design of a LV compensation
cubicle
In addition to the rules and standards concerning
production of electrical switchboards the LV
correction switchboards require the
consideration of specific constraints.
1- The Varpact compensation
modules (see pages 40 to 42)
b mounted, pre-cabled and tested in the factory
b adaptation in all cubicle types
b perfect association of components
The Varplus² capacitors
(see pages 43 and 44)
Their positioning must ensure proper ventilation.
Their sizing must take into account ambient
conditions (harmonics, temperature, etc…)
The contactors (see pages 38 and 39)
They must be suited to capacitor control.
Schneider Electric have designed and tested
specific contactors (Telemecanique) for this
application.
Their control voltage must be monitored in order
to prevent rapid reclosing.
2- The detuned reactors (DR)
(see pages 33 to 35 and 45)
They must be chosen according to harmonic
stresses and installed in order to avoid, as far as
possible, capacitor temperature rise.
The DR temperature sensor must be connected
so that the step can be disconnected if the
temperature is too high.
To not respect one of these 7 rules can shorten the operating life of the capacitors (in a few months) as a result
of an excessive temperature, harmonic stresses or an over voltage due to the wrong setting of the controller.
It can lead to the rupture of the capacitors, contactors, wirings or detuned reactors.
In the worst case, this can lead to fire.

Key points and risks
3- Ventilation (see pages 46 to 49)
It must be efficient in order to keep operating
temperature lower than maximum permissible
temperature of components.
4- The power factor controller
(see pages 36 and 37)
Its functions must be adapted to the capacitor
bank characteristics: number and power of steps,
sequence, etc. The time delay must be adapted
to capacitor discharge time.
Time delay must be set to a minimum
of 50 secondes (see page 11).
5- Low voltage network
(see pages 6 to 8)
Network characteristics, and in particular network
harmonic pollution, must absolutely be taken into
account when choosing capacitors and detuned
reactors (if any).
6- Tests to be done after
production of the bank (see p. 55 to 60)
At the end of the manufacturing process,
a LV switchboard must undergo various routine
inspections and tests in the factory, following an
established programme.
The switchboard must comply with :
b the appropriate standards
b the design file (drawings, diagrams and
specific requirements)
b manufacturer mounting instructions
b in-house instructions.
7- Maintenance must be done
every year
One month after energising, check:
b contactor terminal tightening torques.
Each year check:
b general cleanliness of the equipment
b filters and ventilation system
b terminal tightening torques.
b proper working order of switching and
protective devices
b temperature in the premises:
-5 °C to +40 °C max
b capacitor capacitance, consult us if the
capacitance value has changed by more
than 10 %.

Reactive power
Power definition
Network characteristics
Network voltage and frequency are the basic factors that determine the size
of an LV compensation cubicle. The reactive power Q varies according to
the squared voltage and the frequency.
Q = U2 x C x ω
C = capacitance
ω = 2 πf
1
f = network frequency
It is calculated:
b either from the electricity bills, to avoid paying for the reactive energy
b or from tan ϕ and a target tan ϕ’.

Electrical network pollution Choice of compensation type
Devices using power electronics (variable speed drives,
rectifiers, UPS, arc furnaces, fluorescent lamps, etc.)
circulate harmonic currents in electrical networks.
Such harmonics can interfere with the operation of many
devices. Capacitors are highly sensitive to harmonics.
A high level of harmonic pollution causes capacitors to
overheat and age prematurely (breakdown).
Different types of compensation must be chosen
according to the power of the harmonic generators.
DB109690
Compensation equipment can be of three types (Classic, Comfort,
Harmony), depending on the level of network harmonic pollution.
It can be selected as follows:
b according to the Gh/Sn ratio:
Example 1
U = 400 V P = 450 kW
Sn = 800 kVA Gh = 50 kVA
Gh
-------- = 6,2 %
V Classic equipment
Sn
Sn: apparent power of the transformer.
Gh: apparent power of harmonics-generating receivers
(variable speed motors, static converters, power
electronics, etc.).
Qc: power of the compensation equipment.
U: network voltage.
Example 2
U = 400 V P = 300 kW
Gh
-------- = 18,75 %

Electrical network pollution Choice of detuned reactor tuning
frequency
General
DB110651
The detuned reactors (DR) are designed to protect the capacitors by
preventing amplification of the harmonics present on the network.
They must be connected in series with the capacitors.
The detuned reactors generate an overvoltage at the
capacitor terminals. Capacitors of at least 480 V must be used
for a 400 V network.

Technical data
Choice of tuning
The tuning frequency fr corresponds to the resonance frequency of
the L-C assembly.

fr = ------------------2π LC
We also speak of tuning order n.
For a 50 Hz network:
DB110653
fr
n = ---------------50 Hz
b the tuning frequency chosen must ensure that the harmonic current
spectrum range is outside the resonance frequency
b it is essential to ensure that no remote control frequencies are disturbed.
The most common tuning orders are 3.8 or 4.3 (2.7 is used for 3rd order
harmonics).

Physical and electrical control
The Varlogic power factor controllers continually measure the reactive
power of the system and switch the capacitor steps ON and OFF to obtain
the required power factor. Their ten step combinations enable them to
control capacitors of different powers.

These combinations ensure accurate control, by reducing:
b the number of power factor correction modules
b labour.
Optimising the control in this way generates considerable financial benefits.

Control and monitoring
system
Safety delay
The Varplus2 capacitors have an internal discharge resistor that reduces
the voltage to 50 V in 1 minute after disconnection from the network.
It is essential that the discharge time be observed to prevent the capacitors
and contactors from ageing prematurely.
Automatic capacitor bank
The safety delay of the Varlogic controller must be set to a minimum of
50 seconds.
When the supply to the contactors is separate or different from the supply
to the controller, the control circuit must be wired to ensure that the
discharge time (60 s) of the capacitor is observed (for example the
contactors and the controller must be disconnected at the same time).
Fixed capacitor bank
In the case of manually controlled capacitors, there must be a system to
ensure that no capacitor can be connected more than once in less than
1 minute.

Contactors
General
DB109701
Capacitor control is accompanied by transient operating conditions
resulting from the capacitor load which, amongst other things, generates a
very high overcurrent equivalent to a short-circuit of short duration.
The use of standard contactors may compromise the safety of persons and
installations.
Telemecanique contactors for capacitor control
The LC1-D•K contactors are specially designed for capacitor control.
They are fitted with a contact block allowing the current to pass on closing
and with damping resistors limiting the current on energisation.
This technology, which is unique, has been patented.
Personal safety
The contactors cannot be operated manually.
The contactors are fitted with covers for protection against direct contact.
DB110656
Safety of installations
The damping resistors are disconnected after the capacitor current
energising peak. A faulty contactor pole therefore does not allow the
permanent current to flow through the resistor and prevents it from burning.
Simplicity and durability
LC1-D•K contactors are a ready-to-use solution that does not require the
installation of shock coils.
Their durability is far greater than that of conventional solutions
(300,000 operating cycles at 400 V).
4
If specific contactors cannot be used to control the
capacitors, then energising current limiting reactors must be
used. Please consult the contactor manufacturer.
Note: LC1D contactors not incorporating a preinstalled resistor can be used with
detuned reactors.
The inductance of the detuned reactor limits the energising current to a value that
can be accepted by the contactor.

Ventilation for capacitor banks with detuned reactors
DB114165
This equipment must always include a forced ventilation system.
The DRs must be installed:
b in a separate enclosure
b or in the same enclosure as the capacitors, but in a separate
compartment, or possibly above the capacitors.
The part of the enclosure containing the capacitors must be ventilated
according to the standard capacitor bank rules, see page 45.
The part of the enclosure containing the DRs must be ventilated according
to the dissipated power.
The minimum air flow must be: F = 0.3 x Ps
(Ps = power dissipated by the DRs), see page 33.
b the DR temperature sensor must be connected so that the step
can be disconnected if the temperature is too high
b always let a gap of 100 mm between the back of the bank and the wall.
It allows to have a good ventilation.
Example
250 kvar 400 V DR capacitor bank, tuning 190 Hz,
in 1 x 50 kvar + 2 x 100 kvar:
b DR compartment: forced ventilation
Ps = 300 + 2 x 450 = 1200 W
F = 0.3 x Ps = 0.3 x 1200 = 400 m3/h
b capacitor compartment: forced ventilation
(cubicle: 600 x 400 x 2000)
fan rate: 0.75 x 250 = 187.5 m3/h.

Ventilation system
Derating for an ambient
temperature 50 °C
Compensation installation can be provided for the following operating
conditions:
b maximum temperature in the electrical room: 50 °C
b average temperature over 24 hours in the electrical room: 45 °C
b average annual temperature in the electrical room: 35 °C
b minimum temperature: -5 °C
b maximum altitude: 1000 m.
The following precautions must be taken:
b ventilation must be forced, irrespective of the power, and the ventilation
rate increased by 25 % (see the rules on pages 46, 47 and 48):
v classic or comfort equipment consisting of modules or capacitors:
rate (m3/h) = 0.75 x Q (kvar) x 1.25, whatever the power of Q
v harmony equipment consisting of Varpact harmony modules:
rate (m3/h) = 2.5 x Q (kvar) x 1.25
v harmony equipment consisting of components (capacitors + DR):
- capacitor compartment rate: see rule point 1
- DR compartment rate: (m3/h): 0.3 x Ps x 1.25
b the capacitor voltage must be higher than that normally required
(minimum 10 % higher than that specified by the normal dimensioning
rules)
b the DR temperature sensor must be connected so that the step can be
disconnected if the temperature is too high
b the contactors must be derated, the operating current must be increased
by 10 % with respect to the maximum constant current of the step.
Example: 30 kvar 400 V step, classic range, rated current = 43.3 A:
Imp = 1.36 x 43.3 = 58.9 A.
At a maximum ambient temperature of 50 °C, the contactor must be able to
accept a current of 58.9 x 1.1 = 65 A
b the cables must be appropriate for a current of at least 1.5 times the rated
current of the capacitor at a minimum temperature of 60 °C.

Choice of cables
Power and auxiliary circuits
Step power cables
Flexible, rigid or semi-rigid copper cables are generally used inside the
switchboard.
A U 1000 V cable (insulation 1000 V) is recommended.
For a working voltage that is less than half the insulation voltage of the
cable, i.e. < 500 V, these cables are considered to be class 2.
They can therefore be flanged directly onto metal supports without the use
of an insulating material.
The cable cross-section must be compatible with:
b the current to be carried
b the ambient temperature around the conductors.
Dimensioning rules:
b the ambient temperature in the electrical room must not exceed 40 °C:
the cables must be appropriate for a current of at least 1.5 times the
capacitor current at a temperature of 50 °C
b the ambient temperature in the electrical room must not exceed 50 °C:
the cables must be appropriate for at least 1.5 In at a temperature of 60 °C.
Auxiliary circuits
Unless otherwise stated in the specifications, the following cable crosssections are recommended for the auxiliary wiring:
b 1.5 mm2 for the auxiliary voltage circuits
b 2.5 mm2 for the auxiliary current circuits.
Capacitor bank connection cables
Dimensioning current
The cables must be appropriate for a current of at least 1.5 In.
Cross-section
It must be compatible with:
b the ambient temperature around the conductor
b the method of installation (trunking, duct, etc.).
See the cable manufacturer's recommendations.

recommendations
Installation recommendations
DB110662
b the CT current transformer must be installed upstream of the installation
to be compensated
b the controller voltage should be set between L2 and L3 and the CT to
phase L1
b the capacitor bank wiring diagram should be designed to ensure that the
time required to discharge the capacitors is observed (minimum 1 minute),
for example in the event of a loss of contactor auxiliary voltage
b if the installation comprises two or more supply transformers, a summing
CT that will take all the energy consumed by the installation into account
must be provided. The ratio to be used to calculate the C/K is the sum of
the ratios of the various measuring CTs
b if the installation includes a generator set, a contact will disconnect the
capacitor bank in the event of generator set operation.
The best method is to use it to cut off the supply to the controller.

Current transformers and C/K
Calculation of the response current C/K for power factor
controllers
All the Ct.A, Ct.B, Ct.C and Ct.D current transformers must have
the same ratio (same primary and secondary 5 A).
C = current of the first capacitor bank step.
K = current transformer ratio.
Assumptions
b transformer 1 = transformer 2 = 1600 kVA
b network: 400 V 50 Hz
b capacitor bank A = 300 kvar 400 V, 5 x 60 kvar
b capacitor bank B = 250 kvar 400 V, 5 x 50 kvar
Calculation of the current transformer ratio
Transformer rated current: 160000/400/1.732 = 2310 A.
The transformer primary current must therefore be greater than 2310 A.
A transformer with a primary current of 2500 A should therefore be used.
The transformer secondary current must be 5 A.
We therefore obtain: Ct.A = Ct.B = Ct.C = Ct.D = 2500/5 A.
Choice of summing current transformers
Ct.E = Ct.F = (5 + 5)/5 A.
Calculation of C/K for capacitor bank A
Ca = first step current = 60000/400/1.732 = 86.6 A.
Ka = (Ct.A primary + Ct.C)/5 = 1000.
Ca/Ka= 86.6/1000 = 0.086.
Calculation of C/K for capacitor bank B
Cb = first step current = 50000/400/1.732 = 72 A.
Kb = (Ct.B primary + Ct.D primary)/5 = 1000.
Cb/Kb = 72/1000 = 0.072.

Tests to be done
Principle
The means
Practical rules
At the end of the manufacturing process, a LV switchboard must undergo
various routine inspections and tests in the factory, following an established
programme.
The switchboard must comply with:
b the appropriate standards
b the design file (drawings, diagrams and specific requirements)
b manufacturer mounting instructions
b in-house instructions.
Test conditions
Tests must be carried out in a clearly defined
area, in compliance with applicable legislation
or regulations, by qualified personnel.
DD382359
Inspection means
Inspection is carried out in a special area reffered to as the test platform
which is set aside for final testing. All inspectors must first attend a special
training course and must be qualified for working in the proximity of live
parts.
The necessary parts should be suitable for the purpose, correctly calibrated
and in good working order:
b dielectric test station
b megohmmeter
b multimeter
b capacitance meter
b torque wrench
b controller test bench…

Carry out all the compulsory inspections and tests and in particular the
three routine tests specified by the IEC 60439-1 standards.
They complement any type tests which may have been carried out
previously by the manufacturer.
Standard IEC 60439-1 defines 10 tests to be carried out on electrical
switchboards:
b 7 type tests
b 3 routine tests.
The 7 type tests must be carried out in laboratories and test platforms on
cubicles, using real working configurations: complete cubicles fitted with
standard components and equipped with Varplus² capacitors.
The assembly instructions and the 3 routine tests (described below)
provide the necessary proof that the switchboard is of the Type Tested
Assembly (TTA) or Partially Tested Assembly (PTA) type, and in
compliance with standards.
1st routine test
Inspection of the assembly, including
inspection of wiring and, if necessary,
an electrical operation test.
Conformity
b conformity of the finished switchboard to the drawings, part lists and
diagrams:
v number, type and rating of devices
v conformity of cabling: auxiliary and power circuit connections
v quality of cables: conductor cross-section, crimping and tightness
v marking of conductors and devices.
Visual inspection
b check clearances and creepage distances at connections or part
of busbars
b check the degree of protection. Presence of protective elements,
according to requirements (canopy, gasket, front plate, etc.).
No enclosure infractions (cut-outs, holes, etc.) that might compromise
the original degree of protection
b check the presence of a name plate or technical documentation showing
the manufacturer’s name, the project identity number and all the technical
specifications relevant to the LV correction switchboard (kvar, voltage,
frequency…).
Electrical operation
b inspect the cables and check the proper operation of the LV correction
switchboard, preferably using a “controller test bench” (attached diagram).
b capacitance measurement : check the capacitance of each step
one measurement between two capacitor terminals is sufficient:
Q = 2 x U2 x C x w (C = capacitance, measured between two terminals).

The tests
2nd routing test
Practical rules
Insulation testing
Dielectric test :
All devices must be connected, with the exception of those incapable of
withstanding the test voltage (disconnect the controller). Tests must be
done with all the contactors closed. For a switchboard with voltage rated up
690 V, apply a test voltage of 2500 V - 50 Hz for 1 second minimum,
between all the live parts and the interconnected frames of the assembly.
DD382356
Tests to be done
Note: due to capacitor presence, the test must be performed between
the 3 short-circuited phases and the earth.
The tests are satisfactory if there is neither puncture nor flashover between
the various parts being tested.
DD382361
Dielectrometer.
Alternative solution:
If the switchboard is not subjected to a dielectric test, an insulation
measurement must be taken using an insulation tester, with a voltage of at
least 500 V (DC). The minimum insulation resistance value must be higher
than 1000 ohms/V.
Multimeter.
3rd routine test
Protective measures
Check for the presence of barriers to protect against direct and indirect
contacts with live parts.
Visually check that:
b contact washers have been used on all assemblies
b earthing wires have been fitted to doors
b the PE conductor is present and must be connected.
Finishing
Clean the inside of the switchboard
Check presence of switchboard identification markers
Check external appearance : scratches, paintwork, etc.

Reports
Practical rules
Create a non quality input document used to
quantify faults, evaluate their importance and
assign them to relevant department that must
take the necessary action to ensure
conformity of the electrical switchboard.
Conformity of production:
b draw up a list of missing items
b draw up a list of equipment which will be dispatched separately from the
switchboard.
8
58
Conformity of operation:
b issue a test report
b this report notes any anomalies detected and the required corrective
measures
b establish with the customer, a check list of all the points to be checked
(example enclosed)
b issue a test report that remains in the panel-builder’s possession but that
can be supplied on request
b this report certifies that all the tests have been carried out and avoids
repeating all tests a second time once on site.
Each panel-builder has his own test documents.
