Product Description

Industrial Voltage Stabilizer

Introduction:

Voltage fluctuation is a common phenomenon in every part of the country. The industrial units running round the clock, usually face the problem of low and high voltage. 90% of industrial load is of motors. Electric motors draw considerably high current at low & high voltage. This higher current affects the electrical motors (particularly smaller capacity 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 equipments.
  • For smooth continuous operation of motors, overload relays are usually set at 20% higher setting.

ADVERSE EFFECTS OF SINGLE PHASING

  • The line current increases by 1.5 times.
  • If the relay setting is at 15-20% higher than actual operating current then the relay will take 4-6 minutes to trip.
  • The motor (particularly smaller capacity motors upto 7.5 H.P.) cannot withstand this high current for such a long time and in most of the cases it burns out before the relay trips.
  • Heavy short circuit current flows through the relays, contactors, cables etc.
  • Under this condition when the relay, contactor trips, they produce sparks and some times bursts..
  • This further damages the switchgear and in some of the cases may cause fire also.

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 motor can withstand the high current for this period and will be safe. Also, the relays, contactors, switch gears, etc. Incorporated with the motor will be safe.
