PARTIAL DISCHARGES IN A STATOR UNDER SYNTHEZISED VOLTAGE WAVEFORMS

Paper i proceeding, 2013

This paper introduces a novel way of processing results of measurements of partial discharges (PDs) under the action of pulse width modulated waveforms (PWM) that opens for a flexible analysis of data since voltage shapes appearing in-service can be utilized. Several waveforms gradually smoothened towards a sinusoidal voltage shape are exploited to characterize PD properties in the stator of a three phase motor.
