摘要

从1979年开始，共有24个新的水轮发电机定子棒绕组配备了80pf永久耦合器，用于在线局部放电测量。本文总结了多年来局部放电特性的一些变化，并将这些变化与绕组的状况联系起来。

Tracking stator bar condition by on-line partial discharge measurements

A total of 24 new stator bar windings in hydrogenerators were equipped with 80 pF permanent couplers for on-line partial discharge measurements beginning in 1979. This paper summarizes some of the changes in the PD characteristics that have occurred over the years and correlates significant changes with the condition of the windings.
