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

Key words: metering, error, connection mode
