line vltage of three phase distribution transformer is 433v
and phase voltage is 250v,but we required 230v for domestic
distribution,then how we reduce phase voltage of
transformer
Answer Posted / govardhan reddy
we use individual phase for 230v but 250 R.Y.B R=230V Y= 230V.B230V BUT TOTAL 690V BUT ONLY VOLTAGE 230V
INPUT VOLTAGE 440V TRANSFORMER OUT PUT VOLTAGE 230V
