Abstract
On-line monitoring of partial discharge (PD) is useful in indicating the condition of electrical insulation of large generators. To ensure correct PD monitoring, electrical noise must be rejected. In this paper, after a brief review of progresses in on-line PD monitoring technique for electrical machines, novel noise rejection techniques were presented. PD monitoring results from generators in Qinling Power Plant were also given
