Automatic Voltage Controller

power electrical & controls (pec) is known for reliability and continuous improvement in the field of rolling contact type automatic voltage controller, servo voltage stabilizers. Indian power servo voltage stabilizer primarily consists of the following 

linear, vertical rolling contact voltage regulator, double wound buck / boost type series transformers, electronic control circuit module type and monitoring panel.

1. higher current produces higher losses in electrical motors which cause premature failure of winding.
2. these higher losses of electric motors also increase the losses of cables, switches, transformers and other associated equipment.
3. 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.
