why a three phase transformer cant rotate like three phase motor
Answer Posted / mohammad farman khan
Because Transformer only transfer load from higher level to
lower level in technical can say Transformer can stepup and
step down the voltage. so, this is call static device not
moving device.Configuration of transformer is Dry type Oil
type for distribution of load with diffent cooling
process . Three phase motor has rorating field through
shaft of motor.Due to this cause transformer rating always
in ative load (KVA) not in Real Load (KW).and Motor has
name with real load and HP rating.
