Introduction
While the electrical energy is getting
more scarce and expensive in the developing countries,
the need for power factor improvement by installing
capacitors is well understood by the users.
The improved power factor means: ·
● Reduced line losses
● Improved voltage profile
● Reduced system current
● Reduced cable sizes
● Optimum usage of transformer · Monetary
saving.
We are pleased to offer an all New SquareCap Series of
Power Factor Correction Capacitors with enhanced
performance.
It helps you to achieve better economy by selecting an
application specific capacitor type.
The SquareCap Capacitor series is now available in three
designs viz. ENDC : EPCOS
Normal Duty Capacitor for normal inductive linear loads.
EHDLL: EPCOS Heavy Duty Long Life Capacitor for
loads exhibiting some amount of non-linearity, presence
of harmonics, medium size industries.
ESHDC: EPCOS Super Heavy Duty Capacitor for
non-linear arduous and fluctuating loads and systems
containing higher degree of harmonics.
SquareCap PFC Capacitors are ISI approved and comply
with IS 13340 and latest IEC specifications.
Basic Construction of the Capacitor
1.Film
The three layer Metalized (Silver-Zinc -Alluminium)
Polypropylene Film (MPP) with heavy edge is manufactured
in-house on the latest technology machines. This gives
advantages of higher stability obtained from Zinc and
longer shelf life obtained from Alluminium. Heavy edge
construction of the film provides a better bonding
between electrode and metal endspray (scooping), thereby
enabling an increase in current carrying capacity and
ensuring better withstanding to the electro-mechanical
stress that occurs due to switching surges
2. Winding
The basic single phase capacitors are wound on computer
controlled automatic winding machines and impregenated
with polyurethane resin (dry technology). Thus
ionisation and carona discharge are eliminated resulting
in capacitors with highly stable characteristics and
long life. 3. Safety Systems
A) Burst proof safety device -To prevent the
capacitor from bursting in case of permanent breakdown
caused by very high voltage in repetitive peaks and
which can not be "self - healed" by the selfregenerative
property, the capacitor is provided with a safety
switching
device, which disconnects the capacitor from the power
source. When the internal pressure increases to an
unsafe level it produces expansion of the bellow and
snapping of the inner connection to the supply terminal,
thereby cutting off the supply and avoiding possible
bursting. (See Fig. A)
B) Self-healing property - if the dielectric breakdown
strength is exceeded locally at weak points, at pores or
impurities in the dielectric, a dielectric breakdown
occurs. The energy released by the arc discharge in the
breakdown channel is sufficient to totally evaporated
the thin metal coating in the vicinity of the channel.
The rapid expansion of the plasma in the breakdown
channel causes it to cool within few microseconds, thus
quenching the discharge. This results in formation of
insulated region around the faulty area thus the
capacitor regains its full operation ability.
C) Due to polyurethane resin filling and non use of oil
or PCB there is no risk of fire caused by spurting or
leaking oil. In ecologically sensitive applications this
design (dry) is a must.
4. Modular Construction
Single units in excess of 6KVAr are made up of the
required number of basic single phase modules. These are
housed in a single metallic container and are connected
to the three terminals which are brought out through the
terminal block. This construction enables easy and
inexpensive repair at site and also considerably saves
on spares inventory cost.
5. Inductor coil
For rating of 6KVAr and above each single phase
capacitor module is provided with an inductor coil to
control the inrush current to the capacitor,
particularly in case of parallel switching and automatic
control applications. This feature ensures long-term
stability of KVAr output and extended life.
6. Discharge Resistor
All capacitors are provided with discharge resistors in
order to discharge the capacitor to voltage less than
50Volts within one minute of disconnecting the supply.
However, all capacitor terminals must be properly
discharged before handling them.
EPCOS Super Heavy Duty Capacitor (Double Dielectric
Type)
These capacitors meet the demands
of heavy duty industrial loads. These loads are of the
type, rectifiers, arc or induction furnaces, large
rolling mills, cement factories, textile spinning mills,
welding divisions etc. The basic reason which makes
these loads arduous in nature is that, each load gives
rise to high over current or higher over voltage in an
irregular manner. Rectifier load or arc furnace
generates harmonic voltages which would impose
continuous and severe over current on capacitors.
In order to build up the correct degree of protection, a
capacitor needs to be given a higher over current and
also higher surge voltage withstand capacity. This dual
consideration has been taken into account to evolve a
different construction of capacitors. This design of the
capacitors has been evolved keeping in mind the basic
simplicity of construction of primary MPP cell and its
superiority in the capital and operating costs. The new
design retains all these features and still raises by
about a factor of two, over current as also the surge
voltage withstand capacity making it a real Super Heavy
Duty Capacitor.
Unit ratings are available from 1 to 50KVAr.
