In which connection the distribution T/F is connected?
a) ▲ / Y b) Y / ▲ c) ▲ / ▲ d) Y / Y
Answer Posted / prashant
Distribution transformers are always D/Y. This is coz while
we are transmitting power from the generation station we
only transmit as R,Y,B. Say in the case of large industries
11 KV supply is given directly which is stepped down using
D/Y transformer. the neutal we take from the Y end
