Servo Controlled Automatic Voltage Controller (Stabilizer)

Servo Controlled Automatic Voltage Controller (Stabilizer) is an equipment to obtain constant voltage tram fluctuating supply system. The industrial units usually face the problem of low & high voltage. 90% of industrial load is of motors. Electric motors draw considerably high current at low & high voltage. This higher current affects the electric motors (particularly smaller capacity motors upto 7.5 H.P.). The installation of the stabilizer and maintaining 390/400 volts, the motor will operate smoothly drawing 15-20% lesser current and corresponding 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. Servo Stabilizers are available in a wide range and various models. The standard three phase models are suitable for balanced & unbalanced supply and loads.
