Partial discharge monitoring is an effective on-line predictive maintenance test for 6 kV motors. An understanding of the theory related to partial discharge, and the relationship to early detection of insulation deterioration is required to properly evaluate this predictive maintenance tool. This paper will present a theory to promote the understanding of partial discharge technology, as well as various implementation and measurement techniques that have evolved in the industry. Data interpretation, corrective actions and application to electrical distribution equipment will also bereviewed.
