Abstract
Defects in operation of the induction motors changes the harmonic components of motor supply current. In this paper, Motor electrical current signature analysis (MCSA) is used to detect the inter- turn short circuits in only one winding of the motor stator. In this paper, a theoretical study was conducted to determine the harmonics resulting from the presence of inter- turn short circuits. An experimental module set of a 220V/380V-50Hz-11kW-4pole three- phase squirrel-cage induction machine has been used to verify the efficiency of this method. The experimental results proved the effectiveness of the proposed method in detecting inter-turn short circuit up to the failure of only two turn.
