why transformer comes only in standard rating like
11kv,33kv,66kv....and not like 33.33kv and so on?
Answer Posted / guest
This is the standard rating of supply companies in India.
So in India you will find 11kv, 33kv and 66kv and above,
But if you go abroad like Saudi its 13.5kv etc.
It all depends on which country you are in. Our country
frequency is 50 cycles per second. But in US or Japan its
60 cycles per second.
