摘要
研制了以ＭＣＳ５１系列单片机为核心的热态电气强度测试仪。介绍了９０°移相法和ＬＥＭ模块的工作原理，设计了系统的硬件线路，开发了软件程序，给出了系统流程框图。
In this paper, we present a heated electrical intensity test meter controlled by the single chip computer MCS51, and describe the principle of the 90 degree phase transfering method and the LEM module. The hardware schematics of the system are implemented, and the software protections are also designed.
