摘要
针对微水电厂电容式电压互感器 (CVT)介损超标现象 ,采用几种接线方式进行了试验研究 ,找出了CVT介损超标的原因 ,提出了减小测量误差的方法。
In view of phenomena of the excess of tgδ index of capacitive voltage transformer (CVT),several wiring schemes have been tested and studied so as to find out the cause of the phenomena,and a method to minimize the measuring error is proposed.
