PD measurements on-site using oscillating wave test system

This paper discusses results of non-destructive dielectric tests using oscillating voltages. In particular, using comparison to discharge detection on HV cables at the conventional power frequency of 50 (60)Hz, the sensitivity and the reproducibility of this new method for on-site testing is discussed. Based on laboratory and on-site tests the usefulness of this PD measuring technique for practical applications is presented.
