When we measure the amount of partial discharge , the accuracy of measurement is varied constantly by outer interference , it ' s important to distinguish partial discharge pulse from interference pulse , so how to judge insulation quality according to partial discharge information became the study direction of many scholars and site personnel 在局部放电量的实际测量中,测量的准确性经常会受到外界干扰的影响。如何干确判断局放脉冲和干扰脉冲成为一个重要环节。如何全面掌握设备内部局放的信息来进行绝缘诊断也一直是很多学者和现场试验人员研究的方向。
