| Rolling contact type voltage regulators are important engineering products which are used to produce a steady output voltage despite fluctuations of input voltage. Rolling contact type automatic voltage regulator (AVR) is suitable both for Indoor and Outdoor installation. These voltage regulators possess superior efficiency, life span, insulation and windings.
The installation of voltage regulator ensures the smooth functioning of the motor which draws 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, contractors, switch gears, etc. incorporated with the motor will be safe.
