Abstract

This article introduces the on-site non-destructive dielectric response technique as a diagnosis tool for in-service high voltage motors. It emphasizes the importance of depolarization current which shall be measured in conjunction with polarization current in order to identify the type of insulation trouble, while the time-domain together with the frequency-domain results give decisive information how healthy the insulation is for continued operation.
