why should we place 9KV lightning arrestors in 11KV
substation ?
Answer Posted / virender
The LA are designed to by pass the high voltage surges so
that the system voltages do not get affected and the
equipment in line are safe. We place 9kv in 11kv substation
becouse it can attract the lightning surges in the 11KV
system with low resistance and can ground quickly.
If anyone want to add more he is welcome.
