摘要

　　电能表本身有很多误差。如电能表潜动、电能表的误差等等。很容易引起计量误差。错误接线包括互感器的误接线、断线、电能表的误接线或断线，无论错在哪里。最终都反映在电能计量装置发生偏差，这个偏差远远大于误差引起的计量误差。所以正确接线很重要。
　　本文从电压和电流的相位关系入手，用分组判别的方法，判别不同的接线方式，简单，易行。判别方法是以中性线接线正确为前提的，但是在实际接线时，中性线也可能接错。如何在不保证中性线接线正确的条件下判别三相四线电能表的接线方式将是以后研究的方向。

Abstract

　　　   
　　　Energy meter itself has a lot of errors. Creep, such as energy meter energy meter error. Can easily lead to measurement error. Faulty wiring transformer miswiring, disconnection, the misuse of the power meter wiring or disconnected, regardless of what went wrong. Eventually reflected in the energy metering device deviation, this deviation is much larger than the measurement error caused by the error. Therefore, the correct wiring is very important.
　　　In this paper, starting from the voltage and current phase relationship with packet discrimination, discrimination of different wiring, simple, easy. Discrimination method is based on the neutral wiring is correct as a precondition, but when the actual wiring, neutral may pick the wrong. How discriminant three-phase four-wire power meter wiring does not guarantee the neutral wiring is correct conditions will be the direction of future research.
