a induction motar has 30-35%
exciting current at
no load but in transformer it is
only 2-3% ofbrated
current why any reason?
Answer / sheikh
Transformer is static equipement not a rotary equipment
hence a little bit current observed which may need due to iron
losses . motor is a active and functional parts whatsoever
on load or off load thereby taking 40% approximatelt as
respect to rated current.
