摘　　要：介质损耗试验是判断电力设备绝缘是否良好的重要手段。随着电力系统运行电压的不断提高,高压电力设备传统的10 kV介质损耗试验已不能反映额定运行电压下设备绝缘特性的变化。以实验室试验为基础研究750 kV CVT额定电压下介质损耗试验的方法,为以后的现场试验提供方法和数据参考。Dielectric Loss test is an important means for detecting insulation condition of electrical equipment. With the continuous increase of operating voltage of power system, traditional 10 kV dielectric loss test for high-vohage electrical equipment can＇t reflect the difference of the insulation behavior of equipment under rated operating voltage. This paper studies the dielectric loss test of 750 kV CVT under rated voltage based on lab-scale experiments, and provides test methods ＆ data reference for field test.
