Reactive energy management
In electrical networks, reactive energy results in increased line currents for a given
active energy transmitted to loads.
The main consequences are:
●● Need for oversizing of transmission and distribution networks by utilities,
●● Increased voltage drops and sags along the distribution lines,
●● Additional power losses.
This results in increased electricity bills for industrial customers because of:
●● Penalties applied by most utilities on reactive energy,
●● Increased overall kVA demand,
●● Increased energy consumption within the installations.
Reactive energy management aims to optimize your electrical installation by
reducing energy consumption, and to improve power availability.
Total CO2 emissions are also reduced.
Utility power bills are typically reduced by 5 % to 10 %.

Power Factor Correction
Every electric machine needs active power (kW) and reactive power (kvar) to
operate. The power rating of the installation in kVA is the combination of both:
(kVA)² = (kW)² + (kvar)².
The Power Factor has been defined as the ratio of active power (kW) to apparent
power (kVA).
Power Factor = (kW) / (kVA).
The objective of Reactive Energy management is improvement of Power Factor,
or “Power Factor Correction”.
This is typically achieved by producing reactive energy close to the consuming
loads, through connection of capacitor banks to the network.

Principle of reactive energy management
DE90087.eps
All AC electrical networks consume two types of power: active power (kW)
and reactive power (kvar):
• The active power P (in kW) is the real power transmitted to loads such
as motors, lamps, heaters, computers, etc. The electrical active power
is transformed into mechanical power, heat or light.
• The reactive power Q (in kvar) is used only to power the magnetic
circuits of machines, motors and transformers.
+
In this representation, the
Power Factor (P/S) is equal
to cosj.
The apparent power S (in kVA) is the vector combination of active and
reactive power.
The circulation of reactive power in the electrical network has major
technical and economic consequences. For the same active power P,
a higher reactive power means a higher apparent power, and thus
a higher current must be supplied.
Due to this higher
supplied current,
the circulation of
reactive energy

Benefits of reactive energy management
Optimized management of reactive energy brings economic and
technical advantages.
Savings on the electricity bill
> E
liminating penalties on reactive energy and decreasing kVA
demand.
> R
educing power losses generated in the transformers and
conductors of the installation.
Example:
Loss reduction in a 630 kVA transformer PW = 6,500 W with an initial
Power Factor = 0.7.
With power factor correction, we obtain a final Power Factor = 0.98.
The losses become: 3,316 W, i.e. a reduction of 49 %.
Increasing available power
A high power factor optimizes an electrical installation by allowing
better use of the components. The power available at the secondary of
a MV/LV transformer can therefore be increased by fitting power factor
correction equipment on the low voltage side.
The table opposite shows the increased available power at the
transformer output through improvement of the Power Factor from 0.7
to 1.
Reducing installation size
Installing power factor correction equipment allows conductor
cross-section to be reduced, since less current is absorbed by the
compensated installation for the same active power.
The opposite table shows the multiplying factor for the conductor
cross-section with different power factor values.

Reducing voltage drops in the installation
Installing capacitors allows voltage drops to be reduced upstream of
the point where the power factor correction device is connected.
This prevents overloading of the network and reduces harmonics, so
that you will not have to overrate your installation.

Power Factor Correction
guideline
Method for determining
compensation
The selection of Power Factor Correction equipment can follow a
4-step process:
• Calculation of the required reactive energy.
•
Selection of the compensation mode:
- Central, for the complete installation
- By sector
- For individual loads, such as large motors.
• Selection of the compensation type:
- Fixed, by connection of a fixed-value capacitor bank;
- Automatic, by connection of a different number of steps, allowing
adjustment of the reactive energy to the required value;
- Dynamic, for compensation of highly fluctuating loads.
• Allowance for operating conditions and harmonics.
DE90091.eps
Step 1: Calculation of the required reactive power
The objective is to determine the required reactive power Qc (kvar) to
be installed, in order to improve the power factor cos φ and reduce the
apparent power S.
For φ’ < φ, we obtain: cos φ’ > cos φ and tan φ’ < tan φ.
This is illustrated in the diagram opposite.
Qc can be determined from the formula Qc = P. (tan φ - tan φ‘), which is
deduced from the diagram.
Qc = power of the capacitor bank in kvar.
P = active power of the load in kW.
tan φ = tangent of phase shift angle before compensation.
tan φ’ = tangent of phase shift angle after compensation.
The parameters φ and tan φ can be obtained from billing data, or from
direct measurement in the installation.
The following table can be used for direct determination.

Example: consider a 1000 kW motor with cos j = 0.8 (tan j = 0.75).
In order to obtain cos j = 0.95, it is necessary to install a capacitor bank with a reactive power
equal to k x P, i.e.: Qc = 0.42 x 1000 = 420 kvar.

Method for determining
compensation
Step 2: Selection of the compensation mode
Supply Bus
The location of low-voltage capacitors in an installation constitutes
the mode of compensation, which may be central (one location for the
entire installation), by sector (section-by-section), at load level, or some
combination of the latter two. In principle, the ideal compensation is
applied at a point of consumption and at the level required at any moment
in time.

The location for connection of capacitor banks in the electrical network
is determined by:
• th e overall objective (avoid penalties on reactive energy
relieve transformer or cables, avoid voltage drops and sags)
• the operating mode (stable or fluctuating loads)
• the foreseeable influence of capacitors on the network characteristics
• the installation cost.
M
Central compensation
The capacitor bank is connected at the head of the installation to be
compensated in order to provide reactive energy for the whole installation.
This configuration is convenient for a stable and continuous load factor.
Group compensation (by sector)
The capacitor bank is connected at the head of the feeders supplying one
particular sector to be compensated. This configuration is convenient for a
large installation, with workshops having different
load factors.
Compensation of individual loads
The capacitor bank is connected right at the inductive load terminals
(especially large motors). This configuration is very appropriate when the
load power is significant compared to the subscribed power.
This is the ideal technical configuration, as the reactive energy is
produced exactly where it is needed, and adjusted to the demand.
7
Power Factor Correction
guideline
Method for determining
compensation
Step 3: Selection of the compensation type
Different types of compensation should be adopted depending on the
performance requirements and complexity of control:
• Fixed, by connection of a fixed-value capacitor bank
• Automatic, by connection of a different number of steps, allowing
adjustment of the reactive energy to the required value
• Dynamic, for compensation of highly fluctuating loads.
Fixed compensation
This arrangement uses one or more capacitor(s) to provide a constant
level of compensation. Control may be:
• Manual: by circuit-breaker or load-break switch
• Semi-automatic: by contactor
• Direct connection to an appliance and switched with it.
These capacitors are installed:
• At the terminals of inductive loads (mainly motors)
• At busbars supplying numerous small motors and inductive appliances
for which individual compensation would be too costly
• In cases where the load factor is reasonably constant.
Automatic compensation
This kind of compensation provides automatic control and adapts the
quantity of reactive power to the variations of the installation in order to
maintain the targeted cos j. The equipment is installed at points in
an installation where the active-power and/or reactive-power variations
are relatively large, for example:
• on the busbars of a main distribution switchboard
• on the terminals of a heavily-loaded feeder cable.
Where the kvar rating of the capacitors is less than or equal to 15 %
of the power supply transformer rating, a fixed value of compensation
is appropriate. Above the 15 % level, it is advisable to install an
automatically-controlled capacitor bank.
Control is usually provided by an electronic device (Power Factor
Controller) which monitors the actual power factor and orders the
connection or disconnection of capacitors in order to obtain the targeted
power factor. The reactive energy is thus controlled by steps. In addition,
the Power Factor Controller provides information on the network
characteristics (voltage amplitude and distortion, power factor, actual
active and reactive power …) and equipment status. Alarm signals are
transmitted in case of malfunction.
Connection is usually provided by contactors. For compensation
of highly fluctuating loads use of active filters or Electronic Var
Compensators(EVC) are recommened. Contact Schneider Electric for
electronic compensation solutions.
Dynamic compensation
This kind of compensation is required when fluctuating loads are present,
and voltage fluctuations have to be prevented. The principle of dynamic
compensation is to associate a fixed capacitor bank and an electronic
var compensator, providing either leading or lagging reactive currents.
The result is continuously varying fast compensation, perfectly suitable for
loads such as lifts, crushers, spot welding, etc.

Step 4: Allowing for operating conditions and
harmonics
To know more
about the influence
of harmonics
in electrical
installations,
see appendix
page 66
Capacitors should be selected depending on the working conditions
expected during their lifetime.
Allowing for operating conditions
The operating conditions have a great influence on the life expectancy of
capacitors. The following parameters should be taken into account:
• Ambient Temperature (°C)
• Expected over-current, related to voltage disturbances, including
maximum sustained overvoltage
• Maximum number of switching operations/year
• Required life expectancy.
Allowing for harmonics
Depending on the magnitude of harmonics in the network, different
configurations should be adopted. • Standard capacitors: when no significant non-linear loads are present.
• Harmonic rated capacitors used with detuned reactors. Applicable
when a significant number of non-linear loads are present. Reactors are
necessary in order to prevent the amplification of harmonic currents and
avoid resonance.
• Active filters: when non-linear loads are predominant, use of active
filters are recommended for harmonic mitigation. Solutions can be
recommended based on computer simulations or on site measurement
of the network.
Capacitor selection
Different ranges with different levels of ruggedness are proposed:
• "EasyCan": Capacitors for standard operating conditions, and when no
significant non-linear loads are present.
• "VarPlus Can & Box": Capacitors for stringent operating conditions,
particularly voltage disturbances, or when a few non-linear loads are
present. The rated current of capacitors must be increased in order to
cope with the circulation of harmonic currents.
• "VarPlus Box Energy": Specially designed capacitors, for harsh
operating conditions, particularly high temperature.
• Capacitors with detuned reactors: applicable when a significant
number of non-linear loads are present.

system
Low Voltage capacitors with
detuned reactors
Reactors should be associated with capacitor banks for Power Factor
Correction in systems with significant non-linear loads, generating
harmonics. Capacitors and reactors are configured in a series resonant
circuit, tuned so that the series resonant frequency is below the lowest
harmonic frequency present in the system.
For this reason, this configuration is usually called “Detuned Capacitor
Bank”, and the reactors are referred to as “Detuned Reactors”.
The use of detuned reactors thus prevents harmonic resonance
problems, avoids the risk of overloading the capacitors and helps
reduce voltage harmonic distortion in the network.
The tuning frequency can be expressed by the relative impedance of the
reactor (in %), or by the tuning order, or directly in Hz.
The most common values of relative impedance are 5.7, 7 and 14 %
(14 % is used with high level of 3rd harmonic voltages).

The selection of the tuning frequency of the reactor capacitor depends on
several factors:
• Presence of zero-sequence harmonics (3, 9, …)
• Need for reduction of the harmonic distortion level
• Optimization of the capacitor and reactor components
• Frequency of ripple control system if any.
• T
o prevent disturbances of the remote control installation, the tuning
frequency should be selected at a lower value than the ripple control
frequency.
• In a detuned filter application, the voltage across the capacitors is
higher than the system’s rated voltage. In that case, capacitors should
be designed to withstand higher voltages.
• Depending on the selected tuning frequency, part of the harmonic
currents is absorbed by the detuned capacitor bank. In that case,
capacitors should be designed to withstand higher currents, combining
fundamental and harmonic currents.
Effective reactive energy
In the pages relating to detuned capacitor banks, the reactive energy
(kvar) given in the tables is the resulting reactive energy provided by the
combination of capacitors and reactors.
Capacitor rated voltage
Capacitors have been specially designed to operate in detuned bank
configurations. Parameters such as the rated voltage, over-voltage and
over-current
capabilities have been improved, compared to standard configuration.
10
Rated voltage and current
According to IEC 60681-1 standard, the rated voltage (UN) of a capacitor
is defined as the continuously admissible operating voltage.
The rated current (IN) of a capacitor is the current flowing through
the capacitor when the rated voltage (UN) is applied at its terminals,
supposing a purely sinusoidal voltage and the exact value of reactive
power (kvar) generated.
Capacitor units shall be suitable for continuous operation at an r.m.s.
current of (1.3 x IN).
In order to accept system voltage fluctuations, capacitors are designed to
sustain over-voltages of limited duration. For compliance to the standard,
capacitors are for example requested to sustain over-voltages equal to
1.1 times UN, 8 h per 24 h.
VarPlus Can, VarPlus Box, VarPlus Box Energy and EasyCan capacitors have been designed and tested extensively to operate safely
on industrial networks. The design margin allows operation on networks
including voltage fluctuations
and common disturbances. Capacitors can be selected with their rated
voltage corresponding to the network voltage. For different levels
of expected disturbances, different technologies are proposed,
with larger design margin for capacitors adapted to the most stringent
working conditions (VarPlus Can, VarPlus Box & VarPlus Box Energy).
VarPlus Can, VarPlus Box, VarPlus Box Energy and EasyCan
capacitors when used along with Detuned Reactors have to be selected
with a rated voltage higher than network service voltage (Us). In detuned
filter applications, the voltage across the capacitor is higher than the
network service voltage (Us).
The recommended rated voltage of capacitors to be used in detuned filter
applications with respect to different network service voltage (Us) and
relative impedance is given in the table below.
These values ensure a safe operation in the most stringent operating
conditions.
Less conservative values may be adopted, but a case by case analysis is
necessary.

* The maximum life expectancy is given considering standard operating conditions: rated
voltage (UN), rated current (IN), 35 °C ambient temperature.
WARNING: the life expectancy will be reduced if capacitors are used in maximum working
conditions.
Since the harmonics are caused by non-linear loads, an indicator for the
magnitude of harmonics is the ratio of the total power of non-linear loads
to the power supply transformer rating.
This ratio is denoted NLL, and is also known as Gh/Sn:
NLL = Total power of non-linear loads (Gh) / Installed transformer rating
(Sn).
Example:
• Power supply transformer rating: Sn = 630 kVA
• Total power of non-linear loads: Gh = 150 kVA
• NLL = (150/630) x 100 = 24 %
It is recommended to use Detuned Reactors with Harmonic Rated
Capacitors (higher rated voltage than the network service voltage - see
the Harmonic Application Tables) for NLL > 20 % and up to 50 %.
Note: there is a high risk in selecting the capacitors based only on NLL
as the harmonics in grid may cause current amplification and capacitors
along with other devices may fail. Refer to page 66 for further details.

Low Voltage
Capacitors
EasyCan harmonic applications
EasyCan capacitors are designed to work in
slightly polluted networks with detuned reactors.
480 and 525V range of EasyCan is designed to
work with detuned reactors in 400V.
Operating conditions
■■ For slightly polluted networks.
■■ Slight voltage disturbances.
■■ Need of switching frequency up to 5 000 /year.
EasyCan 03.jpg
Rated voltage
In a detuned filter application, the voltage across the capacitors is higher than
the network service voltage (US). Then, capacitors must be designed to withstand
higher voltages.
Depending on the selected tuning frequency, part of the harmonic currents are
absorbed by the detuned capacitor bank. Then, capacitors must be designed to
withstand higher currents, combining fundamental and harmonic currents.
PE90154.eps
The rated voltage of EasyCan capacitors is given in the table below, for different
values of network service voltage and relative impedance.

VarPlus Can harmonic
applications
VarPlus Can capacitors are designed for
applications where higher number of non-linear
loads are present. Higher current carrying
capacity in VarPlus Can allows the operations in
stringent conditions.
Operating conditions
■■ For networks with a large number of non-linear loads (NLL < 50 %).
■■ Significant voltage disturbances.
■■ Significant switching frequency up to 7 000 /year.
VarPlus Can 04.jpg
Rated voltage
In a detuned filter application, the voltage across the capacitors is higher than
the network service voltage (US). Then, capacitors must be designed to withstand
higher voltages.
Depending on the selected tuning frequency, part of the harmonic currents are
absorbed by the detuned capacitor bank. Then, capacitors must be designed to
withstand higher currents, combining fundamental and harmonic currents.
PE90154.eps
The rated voltage of VarPlus Can capacitors is given in the table below, for different
values of network service voltage and relative impedance.

VarPlus Box
harmonic applications
VarPlus Box capacitors are designed for
applications where higher number of non-linear
loads are present. Higher current carrying
capacity in VarPlus Box allows the operations
in stringent conditions. VarPlus Box capactiors
are dedicated for standalone applications.
Operating conditions
■■ For networks with a large number of non-linear loads (NLL < 50 %).
■■ Significant voltage disturbances.
■■ Very frequent switching operations, up to 7,000/year.
PE90154+PE90134_r.eps
Rated voltage
In a detuned filter application, the voltage across the capacitors is higher than
the network service voltage (US). Then, capacitors must be designed to withstand
higher voltages.
Depending on the selected tuning frequency, part of the harmonic currents is
absorbed by the detuned capacitor bank. Then, capacitors must be designed to
withstand higher currents, combining fundamental and harmonic currents.

VarPlus Box Energy Harmonic
applications
VarPlus Box Energy capacitors with detuned
reactors are designed to operate in harsh
environments.
Operating conditions
■■ For networks with a large number of non-linear loads (NLL < 50 %).
■■ Significant voltage disturbances.
■■ Severe temperature conditions up to 70 °C.
■■ Very frequent switching operations up to 10,000/year.
PE90154+PE90134_r.eps
Rated voltage
In a detuned filter application, the voltage across the capacitors is higher than
the network service voltage (US). Then, capacitors must be designed to withstand
higher voltages.
Depending on the selected tuning frequency, part of the harmonic currents is
absorbed by the detuned capacitor bank. Then, capacitors must be designed to
withstand higher currents, combining fundamental and harmonic currents.
The rated voltage of VarPlusBox Energy capacitors is given in the table below, for
different values of network service voltage and relative impedance.

As the detuned reactor is provided with thermal protection, the normally closed dry
contact must be used to disconnect the step in the event of overheating.

Let’s define the service current (IS) as the current absorbed by
the capacitor and detuned reactor assembly, when a purely sinusoidal voltage is
applied, equal to the network service voltage (V).
IS = Q (kvar) / (√3 x US)
In order to operate safely in real conditions, a detuned reactor must be designed
to accept a maximum permanent current (IMP) taking account of harmonic currents
and voltage fluctuations.
The following table gives the typical percentage of harmonic currents considered
for the different tuning orders.

Contactors
TeSys contactors
For switching 3-phase capacitor banks,
used for power factor correction
Direct connection without choke inductors
Special contactors LC1 D•K are designed
for switching 3-phase, single- or multiplestep capacitor banks. They comply with
standards IEC 60070 and 60831, NFC 54100, VDE 0560, UL and CSA.
Special contactors
Special contactors LC1 D●K are designed for switching 3-phase, single or
multiple-step capacitor banks (up to 6 steps). Over 6 steps, it is recommanded
to use chokes in order to limit the inrush current and thus improve the lifetime
of the installation. The contactors are conform to standards IEC 60070 and 60831,
UL and CSA.
Contactor applications
Specification
Contactors fitted with a block of early make poles and damping resistors, limiting
the value of the current on closing to 60 In max.
This current limitation increases the life of all the components of the installation,
in particular that of the fuses and capacitors.
The patented design of the add-on block (n° 90 119-20) ensures safety and long life
of the installation.
Operating conditions
There is no need to use choke inductors for either single or multiple-step capacitor
banks. Short-circuit protection must be provided by gI type fuses rated at 1.7…2
In.

Influence of harmonics in

Definition of harmonics
Since the harmonics are caused by nonlinear loads, an indicator for the magnitude of
harmonics is the ratio of the total power of nonlinear loads to the power supply transformer
rating.
This ratio is denoted NLL, and is also known
as Gh/Sn:
NLL = Total power of non-linear loads (Gh)/
Installed transformer rating (Sn)
Example:
> Power supply transformer rating: Sn = 630 kVA
> Total power of non-linear loads: Gh = 150 kVA
> NLL = (150/630) x 100 = 24 %.
The presence of harmonics in electrical systems means that current and voltage
are distorted and deviate from sinusoidal waveforms. Harmonic currents are
currents circulating in the networks and whose frequency is an integer multiple of
the supply frequency. Harmonic currents are caused by non-linear loads connected
to the distribution system. A load is said to be non-linear when the current it draws
does not have the same waveform as the supply voltage. The flow of harmonic
currents through system impedances in turn creates voltage harmonics, which
distort the supply voltage.
The most common non-linear loads generating harmonic currents use power
electronics, such as variable speed drives, rectifiers, inverters, etc. Loads such as
saturable reactors, welding equipment, and arc furnaces also generate harmonics.
Other loads such as inductors, resistors and capacitors are linear loads and do not
generate harmonics.
Effects of harmonics
Capacitors are particularly sensitive to harmonic currents since their impedance
decreases proportionally to the order of the existing harmonics. This can result
in capacitor overload, constantly shortening its operating life. In some extreme
situations, resonance can occur, resulting in an amplification of harmonic currents
and a very high voltage distortion.
To ensure good and proper operation of the electrical installation, the harmonic
level must be taken into account in selecting power factor correction equipment.
A significant parameter is the cumulated power of the non-linear loads generating
harmonic currents.
Taking account of harmonics
The percentage of non-linear loads NLL is a first indicator for the magnitude of
harmonics. The proposed selection of capacitors depending on the value of NLL is
given in the diagram below.

A more detailed estimation of the magnitude of harmonics can be made with

of capacitors shall be selected:

The capacitor technology has to be selected according to the most restrictive measurement.
Example, a measurement is giving the following results :
- THDi = 15 % Harmonic solution.
- THDu = 3.5 % VarPlus solution.
Harmonic solution has to be selected.

Figure 1 - (a) Metal layer - (b) Polypropylene film.
Self-healing is a process by which the capacitor restores itself in the event of a
fault in the dielectric which can happen during high overloads, voltage transients
etc.
When insulation breaks down, a short duration arc is formed (figure 1).
DE90174
The intense heat generated by this arc causes the metallization in the vicinity of the
arc to vaporise (figure 2).

Protection Devices in
APFC Panel
Over voltage
In the event of an over voltage, electrical stress on the capacitor
dielectric and the current drawn by the capacitors will increase.
The APFC equipment must be switched off in the event of over
voltage with suitable over voltage relay / surge suppressor.
Over Current
Over current condition is harmful to all current carrying
components. The capacitor bank components must be rated
based on the maximum current capacity. A suitable over current
relay with an alarm function must be used for over current
protection.
Short circuit protection
Short circuit protection at the incomer of the capacitor bank must
be provided by devices such as MCCB's and ACB's.
It is recommended to use MCB or MCCB for short circuit
protection at every step.
Thermal Overload
A thermal overload relay must be used for over load protection
and must be set at 1.3 times the rated current of capacitors (as
per IEC 60831).
In case of de tuned capacitor banks, the over load setting is
determined by the maximum over load capacity of the de tuning
reactor. (1.12 = 4.2(14%), 1.19 = 3.8(7%), 1.3 = 2.7(5.7%)).
If MCCB's are not present, it is recommended to use a thermal
overload relay with the stage contactor to make sure the stage
current does not exceed its rated capacity.
Over Temperature protection
The APFC controller must be tripped with the help of thermostats
in cases the internal ambient temperature of the capacitor bank
exceeds the temperature withstand characteristics of the capacitor
bank components. Reactors are provided with thermal switches
and can be isolated in the case of over temperature conditions.
