Abstract

This paper describes a new technique to compute the equivalent inverse sequence impedance for a working induction motor. The theory of digital formulation of the inverse sequence impedance is given using the traditional procedure and extended to the proposed method using the discrete Fourier transform of two complex sequences. The technique has been implemented on a 230 V/400 V-50 Hz-11 kW three-phase induction machine and gives accurate results for the detection of electrical faults in the stator windings
