The condition prevailing in the blocked rotor test of three phase induction motors resemble those of a transformer whose secondary is short circuited

In the block rotor test of a 3 phase induction motor, measurements are made on the high voltage side and the low voltage side is short circuited so as to get a convenient current which are the same conditions applied in the case of the short circuit test of a transformer. Thus they are said to be resembled each other.
