Answer / jyotirmaya patra

For 11KV Vaccum Circuit Breakers(VCB) are suitable to use.
Now-a-days SF6 (Sulphor Hexa Fluoride) breakers are
available but VCBs are economical than SF6 breakers.

For 33KV - both VCB & SF6 breakers can be used,but SF6
breakers are safer than VCBs. VCBs are more economical

For 66KV - SF6 breakers are the best to use
