In this paper, preliminary results of testing generator stator insulation using PD detection at oscillating voltage waves are presented. Based on laboratory investigation, on a full scale stator insulation system, a comparison of PD behavior: the PD inception conditions and PD levels at 50 Hz AC stresses and at oscillating voltages has been performed. The usefulness of PD detection at oscillating voltage waves has been discussed.
