围绕典型的局部放电类型进行了试验平台的搭建，设计了空气及油中尖－板、板－板、沿面、气隙等多种常见放电模型，通过不同的检测方法对局部放电进行了测试。结合基于脉冲电流法的放电图谱，通过示波器多通道采集的方法，对脉冲电流法、特高频法、超声波法传感器的性能对比，得出了这三种不同的检测方法中测试灵敏度不同的特点。

Aiming at typical partial discharge (PD), this paper build PD test platform. Designed severl common PD model which in oil and air, those model include point-point, plate-plate, surface discharge. Test the PD signal through different methods. Integrate the PD map of pulsating current, by using multiple channel oscillograph acquisition, analyzed the performance of pulsating current sensor, UHF sensor and ultrasonic sensor. This paper reached the peculiarity of three different PD detection methods.
