摘　　要：高频保护是电力系统中普遍采用的保护方式。高频保护的可靠运行,不仅取决于高频保护装置本身,在很大程度上也依赖于高频通道的工作状态。文章针对高频通道可能出现的故障点,介绍了故障检测方法,分析了故障检测原理并介绍了故障检测系统的组成部件。High frequency protection has been widely used in power system. Its reliability not only depends on equipment itself, but relies on the working condition of high frequency channels. Considering the potential faults, this paper discusses the testing methods and the principle of fault detecting. It also introduces the parts and components of the testing system.
