基于六角图的三相三线电能表错误接线判断方法

Method for Judging Wrong Wiring of Three-phase Three-wire Kilowatt-hour Meters Based on Hexagonal Diagram

提出了一种基于六角图的三相三线电能表错误接线判断新方法。根据相位仪测量的电压、电流、相位角等数据,利用六角图法能迅速、便捷地判断出三相三线电能表错误接线的相别和电流方向,并验证测量的准确性,为电能表正确计量提供了支撑。

A new method for judging wrong wiring of three-phase three-wire kilowatt-hour meters based on hexagonal diagram is proposed.According to the voltage,current,phase angle and other data measured by the phase meter,the phase and current direction of the wrong wiring of three-phase three-wire kilowatt-hour meters can be quickly and conveniently judged using the hexagonal diagram method,and the accuracy of measurement is verified,which provides technology support for the correct measurement of kilowatt-hour meters.
