define main transformer?

Answer Posted / ramendra shukla

A Device which tranform the electrical voltage form one
magnitude to another magnitude without changing the supplu
frequency is know as Transformer.
It does so by faraday`s Electromagnetic induction law.
A main x-mer is satuated at generating end the
output of Alternator is connected with this& then its
output is feeded for supply in Y-connection maaner.
