230kv,110kv,33kv,22kv,11kv?

Answer Posted / a.p.nanjappa

standard says as nearaspossible. we maintain just the
outlet of power transformer bushing-10m for all
400,230,110,66,33,11kv.
we adopt counter and mA indicator in the LA grounding,
LA grounding is separately connected to main earth
grounding system
