摘要
分析三相三线和三相四线电能表接线方式的区别,以及对中性点接地方式不同的电力系统电能计量的影响,根据得出的结论分析实际工作中遇到的计量问题。
The paper analyzed the differences of connection mode of electrical energy meter between three-phase three-wire and threephase four-wire, and the effects of different grounded neutral system on electrical energy metering. The measure problems in actual work were analyzed according to the conclusion.
