产生计量误差的接线方式

The connection mode causing metering error

准确是电能计量的基本要求,正确接线是保证计量准确的前提。总结了工作中碰到会引起计量误差而往往被忽视的接线方式,分析了二次回路接地不当引起误差的接线方式,给出了处理措施。

Accuracy is the basic requirement of electricity metering, and correct connection is the precondition for metering accuracy. Some connections modes which can cause metering error but was unnoticed in practice often were summarized. The secondary circuit connection causing error clue to improper grounding was analyzed, and the treatment measures were given in this paper.
