摘　　要：笔者针对110 kV及以上电压等级高压交流油纸绝缘套管频域介电谱的现场测试,阐述了现场电磁干扰机理并提出提高试验电压等抑制电磁干扰影响的方法,研究了套管的频域介电谱特性与试验电压的相关性。换流站和变电站现场实施效果显示提高试验电压可有效抑制套管频域介电谱测试过程的电磁干扰并提高测试结果的准确性。The author introduced the field test of the frequency domain spectroscopy of 110 kV and above high voltage AC oil-paper insulated bushings,and explained the mechanism of electromagnetic interference and proposed measures,such as increasing the test voltage,to suppress electromagnetic interference. And voltage dependence of the frequency domain spectroscopy of high-voltage AC bushings were studied. The method of increasing the test voltage was proved to be effectively in suppress the electromagnetic interference and improve the accuracy of the test result during.
