2 4298What will be the minimum megger value of 1700 KVA Transformer? a) Do megger value varies according to climate conditions and area . b) If megger value is 100 mega ohm is it good for new transfomer. Explain?
4 6037i 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.
