Free metal particle discharge is a partial discharge between metal particles and

metal particles and a partial discharge between metal particles and metal parts.

This type of discharge amplitude distribution is relatively wide, the discharge

time interval is unstable, its polarity effect is not obvious, and there is a

discharge signal distribution throughout the phase of the power frequency cycle.

Suspended potential body discharge

The floating potential body discharge is a partial discharge generated by

loose metal parts. The amplitude of such discharge pulses is stable, and the

adjacent discharge time intervals are basically the same. When the suspended

metal body is asymmetric, the positive and negative half-wave detection signals
