If u ask about BDV Value oil it should be minimum 40KV AS
PER IE STANDARDS. BUT IN INDIA WE MAINTAIN APPROX 50-60KV.

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
