摘要
为研究大型汽轮发电机内部局部放电信号，研制了一套微机辅助的局部放电在线监测系统．系统由传感器、前置放大、信号传输系统、数据采集、处理和显示等部分组成。现场实验表明，该系统可以满足大型汽轮发电机局部放电在线监测的要求．
A computer-aided on- line monitoring system of partial discharge in turbogenerator has been studied It composed of broadband current transducer , preamplifier, transmission line, data acquisition system, signal processor, and display system.Some on - line test results show that this system can meetthe need of on- line monitoring of partial discharge in turbogenerator,
