Long Term Voltage Regulation

In many parts of the world the quality of electrical power is poor or inconsistent. Voltages can vary significantly from nominal values, typically +15%/-20% or more at 380V or 400V, sometimes for several hours at a time.  This causes problems for electrical equipment.

Omniverter has Automatic Voltage Regulator (AVR) solutions to correct such voltage variations based on two different technologies Digit@L AVR which is based on a mechanical system and EY-AVR which uses multi-tap transformers and power electronic tap switching
