摘　　要：对互感器来说,同一试验项目在不同测试接线下得出的数据对其分析诊断故障具有重要意义。为此本文以电磁式电压互感器(PT)介质损耗测试为例,首先通过对电磁式(PT)结构原理、特点及对几种不同接线方式下介损测试接线说明的介绍,其次针对都匀供电局某个变电站110kV线路出线电磁式(PT)预试工作,结合不同介损测试试验数据及各自接线方式下原理、优缺点特性的分析,初步判断该电磁式PT故障位置,最终得出结论的诊断实例。To the mutual transform, the data from the same test items and different test wiring had the important meaning for the fault diagnosis and analysis, In this paper, taking the electromagnetic PT medium loss testing as an example, first introduced its structure principle, characteristics and several different wiring method, then to the 110 kV line PT test work, combined with different medium loss testing data, connection mode, advantages and disadvantages, preliminary confirmed the electromagnetic PT fault location, last this paper reached the conclusion.
