摘　　要：为解决故障指示器的测试问题,设计了一种配电线路故障指示器测试仪。该仪器能实现故障指示器功能和性能的闭环检测,模拟输出最高电压5.77 kV、冲击电流1 kA的各种线路工况特征波形及其谐波,自备通信功能。阐述了该仪器的硬件组成和软件设计,并分析各部分的功能及主要电路的工作方式。For solving testing problem of fault indicator, this paper introduces design one fault indicator tester of distribution line. This instrument is able to realize closed loop detection of function and performance of fault indicator and analog output of signature waveform and harmonic of working condition of various lines with highest voltage of 5.77 kV and impact cur- rent of 1 kA. It is also provided with self-aid communication function. It states hardware composition and software design of this instrument and analyzes functions of various parts and working manners of main circuits.
