Welcome
to Jindal Electricals
Voltage
fluctuation is a common phenomenon in every part of the country. The
industrial units, which are running 24 hours, face the problem of low and
high voltage. 90% of industrial load is of motors.
Electric
motors draw considerably high current at low and high voltage. This higher
current affects the electrical motors (particularly smaller motors upto
7.5 H.P.) in three ways.
|
-
Higher
current produces higher losses in electrical motors which causes
premature failure of winding.
-
These
higher losses of electric motors also increase the losses of cables,
switches, transformers and other associated equipment.
-
For
smooth continuous operation of motors, over load relays are
usually set at 20% higher setting. If single phasing occurs..

INNER
VIEW OF STABILIZER
|
With
the installation of the stabilizer and maintaining 390/400 volts,
the motor will run smoothly drawing 15-20% lesser current and
correspondingly the relay settings can be reduced by 15-20%. In case
single phasing occurs, the relay will trip in 40-50 seconds. The
motor can withstand the high current for this period and will be
safe. Also, the relays, contactors, switchgears, etc. incorporated
with the motor will be safe.
|
WHO
NEEDS A STABILIZER
The
industries which are having acute failure rate of lighting
equipments such as bulbs, chokes, motors (particularly smaller
rating motors upto 7.5 H.P.), contactor coils, etc. definitely
require a stabilizer.
HOW
TO ACCESS HIGHER LOSSES & LOW POWER FACTOR IN INDUSTRIAL UNITS
WITHOUT INSTALLING STABILIZER
|
-
Note
down hourly readings of current and voltage of one motor running
at constant load for 2-3 days. From the different readings, you
will observe that the current drawn by the motors in minimum at
390/400 volts, as compare to the current drawn at other
voltages. This means that power consumed by the motor is minimum
at 390/400 volts.
-
Also
note down hourly readings of voltage and power factor from your
main panel for 2-3 days. From the readings you will observe that
power factor is maximum at 390/400 volts inmost of the readings
in comparison to the higher voltage readings.

If
you find that the above factors are true then you will have
following advantages after the installation of stabilizer.

PAYBACK
PERIOD
Owing
to its high efficiency and associated benefits, the payback period
of Jindal's Servo Voltage Stabilizer is within 6-12 months and
depends upon the input variation and the number of working hours.
DESCRIPTION
OF JINDAL'S MAKE AUTOMATIC VOLTAGE CONTROLLER
Jindal's
Automatic Servo Voltage Stabilizer primarily consists of the
following
|
-
Linear
type continuously variable voltage regulator.
-
Double
wound buckboost transformer.
-
Electronic
control circuit and meter panel.
The
regulator and buckboost transformer are oil cooled, housed in same
or separate sheet steel tanks. Radiators, if necessary are provided
for effective cooling. Their core is built from grain oriented
silicon steel Laminations which keep losses to the minimum and they
are wound with electrolyitic grade copper to minimise the losses,
vacuum impregnated and over dried as per IS.
