I agree with Amritpal Singh Sidhu. i had similar
experience of AVR failure at the site few days ago and i
provided 12volts from the battery. innitially the voltage
was a bit higher than normal but i adjusted the governor of
the DG till i got a normal voltage.

A well system is when , no. of bus bar is less or more. Tell me the concept of it.
