三相四线有功电能表的几种误接线计量分析

Measurement Analysis of Several Wrong Wiring of Three-Phase Four-Wire Active Electric Energy Meter

三相四线有功电能表是供电系统中重要的计量装置,但安装过程的误接线,会造成电能表的计量错误。文章分析了几种电能计量装置的误接线方式并给出相应的功率表达式,计算出计量误差,这样根据抄表电量就可以推算出用户的正确电量。

Three-phase four-wire active energy meter is an important measurement device in the power supply system,but the wrong wiring during the installation process will cause the measurement error of the energy meter.The wrong wiring mode of several electric energy metering devices was analyzedand the corresponding power expression were given.The measurement errorwascalculated so that the user's correct electricity could be calculated according to the meter reading electricity.
