Power factor

results in

Higher energy consumption and
costs,
Less power distributed via the
 network,
Power loss in the network,
Higher transformer losses,
Increased voltage drop in power 
distribution networks.

Power factor improvement

Power factor improvement can be
achieved by

Compensation of reactive power 
with capacitors,
Active compensation – using 
semiconductors,
Overexcited synchronous  machine
(motor /generator).

Types of PFC 

(detuned or conventional)

individual or fixed compensation
(each reactive power producer is
individually compensated),
group compensation (reactive power
producers connected as a group
and compensated as a whole),
central or automatic compen sation
(by a PFC system at a  central point),
mixed compensation.

reactive power compensation systems
(detuned /conventional) are

   installed

for larger loads like industrial machinery.
Such systems consist of a group
of capacitor units that can be cut in
and cut out and which are  driven and
switched by a power  factor controller.

With power factor correction the apparent power

generated

Every electric load that works with
magnetic fields (motors, chokes,
transformers, inductive heating, arc
welding, generators) produces a vary-
ing degree of electrical lag, which is
called inductance. This lag of inductive
loads maintains the current sense (e.g.
positive) for a time even though the
negative-going voltage tries to reverse
it. This phase shift between current
and voltage is maintained, current and
voltage having opposite signs. During
this time, negative power or energy 
is produced and fed back into the 
network. When current and voltage
have the same sign again, the same
amount of energy is again needed to
build up the magnetic fields in induc-
tive loads. This magnetic reversal 

In AC networks (50 /60 Hz) such a
process is repeated 50 or 60 times a
second. So an obvious solution is to
briefly store the magnetic reversal 
energy in capacitors and relieve the
network (supply line) of this reactive
energy. For this reason, automatic

General

The increasing demand of electrical
power and the awareness of the
 necessity of energy saving is very up
to date these days. Also the aware-
ness of power quality is increasing,
and power factor correction (PFC) and
harmonic filtering will be implemented
on a growing scale. Enhancing power
quality – improvement of power factor
– saves costs and ensures a fast 
return on investment. In power distrib-
ution, in low- and medium-voltage
networks, PFC focuses on the power
flow (cos 

Ø

) and the  optimization of

voltage stability by generating reactive
power – to  im prove voltage quality and
reliability at distribution level.

How reactive power is

Power Quality Solution strategy

Along with the emerging demand for
power quality and a growing aware-
ness of the need for environmental
protection, the complexity in the ener-
energy market is increasing: users and 
decision-makers are consequently
finding it increasingly difficult to locate

the best product on the market and to
make objective decisions. It is in most
cases not fruitful to compare catalogs
and data sheets, as many of their 
parameters are identical in line with
the relevant standards. Thus operating
times are specified on the basis of

tests under laboratory conditions that
may differ significantly from the reality
in the field. In addition, load structures
have changed from being mainly linear
in the past to non-linear today. All this
produces a clear trend: the market 
is calling increasingly for customized
solutions rather than off-the-shelf
products. This is where Power Quality
Solutions come into the picture. It 
offers all key components for an 
effective PFC system from a single 
source, together with:

Application know-how
Technical skills
Extensive experience in the field of
power quality improvement
A worldwide network of partners
Continuous development
Sharing of information

These are the cornerstones on which
Power Quality Solutions are built. On
the basis of this strategy, EPCOS is
not only the leading manufacturer of
power capacitors for PFC applications
but also a PQS supplier with a century
of field experience, reputation and 
reliability.

Important Notes

The  following applies  to all products named in this

 

publication:

1. Some parts of this publication contain 

s tatements about

the suitability of our products for certain  areas of appli-
cation

. These statements are based on our knowledge

of typical requirements that are often placed on our prod-
ucts in the areas of application concerned. We neverthe-
less expressly point out 

that such statements cannot be

regarded as binding statements about the suitability
of our products for a particular customer application.

As a rule, EPCOS is either unfamiliar with individual 
customer  applications  or  less  familiar  with  them  than 
 the customers themselves. For these reasons, it is always 
ultimately incumbent on the customer to check and decide
whether an EPCOS product with the properties described
in the product specification is suitable for use in a partic-
ular customer application.

2. We  also point out that 

in individual cases, a malfunc-

tion of electronic components or  failure  before the
end of their usual service life cannot be completely
ruled out in the current state of the art, even if they are
operated as speci fied

. In  customer applications requiring

a very high level of  operational safety and especially in
 customer applications in which the malfunction or failure
of an electronic component  could  endanger human life or
health (e.g. in accident prevention or life-saving systems),
it must therefore be ensured by means of suitable design
of the customer application or other action taken by the
 customer (e.g. installation of protective

  

circuitry or

 redundancy) that no injury or damage is  

 sustained by third

parties in the event of malfunction or failure of an electronic
component.

The  warnings,  cautions  and  product-specific  notes
must be observed.

Data Sheets on the Internet (www.epcos.com/material).

quently, 

the  products  described  in  this  publication

General

APP Capacitor is proven 
technology from more than 30 
years. The combination of
polypropylene film and aluminum 
foil makes the capacitor, more 
robust in varying conditions of the 
load.

The power range varies from 
5 KVAr to 100 KVAr and voltage 
range varies from 240V to
1000V in three phase units. Single 
phase units are also available on 
demand.

The LT-APP capacitors are utilized 
in industry for sustaining large load 
variations, THD and hazardous
