Abstract
PD detection sensitivity is quite an important factor for the PD detection system. In this paper, to compare with the PD detection sensitivity, experiments are carried out using three kinds of insulation defects. Magnitude of detected PD charges is different case by case, however, estimated net charge of PD for the same background electric field is nearly the same.
Equivalent circuit for PD sensitivity is also discussed. The ratio of net charge divided by apparent charge is about 15 for free particle in actual 300kV GIB.
