In this paper, the impact damage to the motors on the course of zero-sequence voltage and its spectrum is presented. Detection signals results from detail analysis of the formula describing this voltage component is induced in the stator windings due to core magnetic saturation and the discrete displacement of windings. Its course is affected by operating both the stator and the rotor. Other fault detection methods, by analysing the spectrum of stator currents, are known and widely applied. The presented method is under investigation, but may be a complement to the other because of easy measurement of the zero voltage for star connected motors. The results of the method are presented by measurements and explained using mathematical modelling for the slip-ring induction motor.
