在当今电晕放电现象检测研究领域中，多数检测方法对检测环境有严苛要求且检测过程中易产生较大误差。针对这一问题，设计了一种高压电晕检测系统，该系统通过对电晕放电产生的电磁波进行检测，由观测波形来判断电晕放电是否发生。重点设计了低噪声放大器和差分放大器等前端硬件部分，另外简单介绍了系统中信号采集和数字信号处理等后端部分，最后检测平台经现场测试具有误差小且能够实现200 m以内电晕放电检测的目标。

In the current research field of the corona discharge detection,Most detection methods need strict condi-tions and make error prone. To this question,a high voltage corona detection system has be designed. The system detects the corona discharge phenomenon through electromagnetic wave and by observing the waveforms to judge whether corona discharge happened. The design emphasis on the design of low noise amplifier and differential am-plifier. In addition,it also introduces signal acquisition and digital signal processing of the platform simply. Through the filed test,this detection platform possesses low error and can achieve about 200 meters corona discharge detec-tion.
