摘　　要：本研究主要探究了绝缘子泄漏电流在线监测系统的设计方案和测试效果。分析结果表明,在温度相同的情况下,空气湿度越高,绝缘子泄露电流的波形畸变情况越明显,高次谐波的幅值波动越大,绝缘子发生污闪的概率越高。This research mainly explores the design scheme and test effect of insulator leakage current on-line monitoring system.The analysis results show that,under the condition of the same temperature,the higher the air humidity,the more obvious the waveform distortion of insulator leakage current,the greater the amplitude fluctuation of higher harmonic,the higher the probability of insulator pollution flashover.
