| 摘 要： | 为检查分级绝缘电压互感器的绝缘缺陷,需要对其进行倍频感应耐压试验。笔者提出了倍频感应耐压试验时试验电压的几种测量方法,对耐压试验中电压互感器的容升电压的产生原因及其对试验的影响进行了分析,对耐压试验的电压持续时间进行了说明,指出耐压试验前后空载试验结果的对比是判断被试电压互感器是否合格的依据。

| Abstract: | Inductive withstand voltage test with double frequency should be done to grad insulated transformer,in order to detect its insulated objection.The paper presented several methods to measure the test voltage in the test,analyzed the causation of capacitance-rised voltage on voltage transformer and its effect,explained the duration of withstand voltage test.It is pointed out that the cross-reference results of unloaded withstand voltage test is criterion for a transformer. |
