局部放电试验对干式绝缘电气设备存在的弱点或缺陷具有很好的检测作用，但常常因为干扰的影响，使测试无法达到满意的效果。
Partial discharge test have good detection effects the weak points and defects of dry insulation inductor, but the test often couldn't attain the satisfied purpose because of the interference.
介绍了故障绝缘子轴向电场分布的计算结果和特点，并给出了实验室检测试验的结果。
The calculation result and the characteristics of the axial electric field distribution of the faulted insulator are described. Testing results at laboratory are given.
试验中分析了污秽、劣化绝缘子位置、绝缘子型式、检测距离等对检测效果的影响。
The influence of pollution, faulty insulator position, insulator type, detection distance to the detection effect was analyzed by the test.
这热量帮助击穿电线绝缘较薄的地方﹐否则线材通过电极而没有被检测到﹐结果在以后的火花测试和高压绝缘试验将会失效。
This heating helps to break down weak spots inthedielectric that otherwise might pass through theelectrodeundetected, only to fail during a later spark orhipottest.
