i am using auto transformer for starting of induction motor
to provide reduse voltages...but the principle of a
tansformer according to definition"which transform energy
to on circuit to another circuit with constant power and
constant frequency". so if i am using reduse voltage then
current obsely hige because power is same.but we use auto
transfarmer for starting of induction motor to give low
current.but here according to definition we are giving hige
current.
