Electricity is the heart beat of any
industry/office and Transformer is the heart of the Company but
today scenario hardly any industry receive HEALTHY ELECTRIC SUPPLY
(Constant Voltage) due to long transmission line, imbalance between
supply & demand of power & poor infrastructure. Higher &
Lower voltages above rated voltage adversely affect the life of the
equipment and consume more power thus increases the burden on the
balance sheet of the company so to solve we have automatic voltage stabilizer, l .t. voltage stabilizer. Generally 90 % of the industrial load
is of motors and the higher current effects the Electric motors (particularly
smaller capacity motors up to 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 & other associated
equipments.
- For smooth continuous operation of motors, over load relays
are usually set at 20% higher setting
|
With the installation of the stabilizer and
maintaining 390/400 volts, the motor will operate smoothly drawing 15 -
20% lesser current and correspondingly the relay setting can be reduced
by 15 - 20%. In case single phasing occurs, the relay will trip in 40 -
50 seconds. The motors 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. L.T. AVR being easy to handle
are installed in all the running units, units having L.T. connections,
units having small H.T. connections. These can be manufactured for
Balance Input Voltage and Unbalanced load or Unbalanced Voltage and
unbalanced load
