三相四线电能表错误接线对电能计量影响分析

Analysis of the Effects of Wrong Wiring on Three-phase Four-wire Electric Energy Meter

根据三相四线有功电能表电能计量原理,结合向量图,分析在错误接线下三相四线有功电能表电能计量与正确接线时的误差值,并采用三相电能表校验装置,对错误接线下的三相四线有功电能表的实际电能计量性能进行验证,对处理实际由于错误接线引起的电能纠纷提供参考。

According to the electric energy metering principle of three - phase four - wire active watt - hour meter and the vector diagram,the error values of three - phase four - wire active watt - hour meter under wrong wiring and correct wiring are analyzed.The actual electric energy metering performance of three - phase four - wire active watt - hour meter under wrong wiring is verified by using three - phase watt - hour meter calibration device.It provides a reference for dealing with power disputes caused by wrong wiring.
