摘　　要：介绍了东莞供电局避雷器带电测试的新方法,并通过新方法对运行中避雷器的泄漏电流及阻性分量测试,成功发现了一起避雷器缺陷,用实例说明无需设备停电也可准确发现设备缺陷的效果,进一步验证了使用避雷器带电测试取代原有的停电预防性试验的可行性。This paper introduces the new method of arrester charged test now in Dongguan Power Supply Bureau, and through the leakage current and resistive component testing, successfully found a lightning protector defects. The example is given to illustrate the new method can achieve the effect to find the defect without equipment power outage, to further validate the use of arrester charged test is feasible to replace the traditional power failure preventive test.
