摘要
本文分析了在变压器铁芯接地断线断时,由于试验等值回路发生了变化,出现了现场测得绝缘电阻及tgδ均增大,吸收比及电容值均减少的现象。
Due to the test equivalence circuit has been changed, when wc do measuring in site, some phenomena appeared in the location where the grounding wire of transformer core is broken, such as insulation resistance and tgδ raise, absorptance and capacitance reduce. In this paper which are analyzed.
