Modern motor protection relays are capable of long term failure monitoring and diagnostics based on information collected by a powerful data acquisition system. This includes predicting life time of motors. This paper presents an advanced algorithm capable of performing such tasks. It is applicable to different types of rotating electric machines depending on their design. The components are: stator turn fault detection and rotor bar fault detection. Detection methods are based on calculating the cross coupled impedance and analyzing the current frequency signature of the motor. The presentation includes a theoretical background, simulated results and testing results performed on a particular physical model.
