Acoustic emission and partial discharges in M-I-M capacitors

conference paper

English

Experimental studies of acoustic emission and current partial discharges in relanex and remicanite insulating foils have been performed under applied constant and ramp voltage. Partial discharges occur only for increasing/decreasing bias voltage higher than threshold voltage about 300 V.Time delay between PD and AE signals can be used to determine the position of PD source.
