Motor current signature analysis (MCSA) is one of the most powerful methods of online motor diagnosis for detecting motor faults. MCSA technique in case of cage rotor induction motors means the analysis of stator-line current spectrum obtained by applying Fourier transform to the stator current waveform in steady-state conditions. The stator-line current frequency spectrum represents, a sort of speaking, an electrocardiogram of an electrical machine. This technique is particularly useful because it is noninvasive, and the search coil is the stator winding of the machine, itself. Using MCSA has advantages such as no estimation of motor parameters and the simplicity of current sensors and their installation.
