Why 66KV is step down to 11KV and then 433v, not directly
66KV to 433v ?

Answer Posted / niresh yadav

:+ As we know that ' from feraday first low when any conductor cut the flux more than flux linkage is more * so when primary side of transformer has 66 kv voltage so indused is high ! In comperision primary turns ratio secondary turns are very low when we change 66 kv to 433 volt than secendary are burns due to induction ! So we convert 66 kv to 11 kv first for protection.
