摘　　要：在ANSI/IEEE标准中,规定在额定频率和10kV有效电压的标准下测试充油高压互感器介损因素。而最近各种高压测试设备制造商推出了工作电压为2.5kV的新型便携式介损因数测试仪,这些机组大多采用电池供电,非常适合用于现场调试测试工作。本文通过在10kV和2.5kV的工作电压下测试了来自不同制造商的各种高压互感器的介损因素,来全面了解在不同电压等级下高压互感器的介损因数差异性。In ANSI/IEEE standard,it is stipulated to test the dielectric factor of oil-filled high voltage transformer under the standard of rated frequency and 10kV effective voltage.Recently,various high voltage test equipment manufacturers have introduced a new portable dielectric loss factor tester with a working voltage of 2.5kV.Most of these units are powered by batteries,which are very suitable for field debugging and testing.In this paper,the dielectric factors of various high voltage transformers from different manufacturers are tested under 10kV and 2.5kV working voltage to comprehensively understand the difference of dielectric loss factors of high voltage transformers under different voltage levels.
