摘要
大型发电机局部放电在线监测的关键技术之一是如何掏现场的各种电磁干扰。本文对现场干扰的特性进行了分析 ,并提出了相应的抑制方法。最后介绍了已成功用于发电机局部放电在线监测仪中的抗干扰系统。
One of the key techniques for on\|line monitoring of partial discharge(PD)in large generators is to suppress various noises in site.In this paper,noises arising in site were analyzed systematically and corresponding noise suppressing techniques were presented.In order to demonstrate the efficiency of the techniques presented,several measurements performed in site were shown.
