摘要
以桂林网区常见的110kV电容式电压互感器为研究对象,应用等效电路法对分压电容器的电容量和介损的测试方法进行分析比较,得出在不拆线的条件下通过C1反接屏蔽,可得到与正接法相同的试验准确度。
Taking the most common 1 lOkV capacitor voltage transformer of Guilin power grid as an example, we analyze the testing method of capacitance and dielectric loss. It is concluded that through the C1 reverse connection shielding,we can get the same test accuracy of straight polarity.
