Model for partial discharges associated with treeing breakdown: I. PDs in tree channels

Abstract

In order to check our physical model for partial discharges (PDs) in a tree channel, the light emission from a PD in an actual tree was observed. The experimental results agreed with the model. By using the model, conditions for the formation of typical phase-amplitude-number (ϕ-q-n) pattern of PDs from treeing was discussed.
