正确接线情况下三相三线电能表负电流现象原因分析

Cause Analysis on Negative Current of Three － phase Three － wire Electric Energy Meter under Correct Wiring

摘要:

针对用电采集系统中正确接线的三相三线电能表负电流现象展开分析，利用计量原理和相量图从功率因数 的角度做出了规律总结，并结合负荷性质和现场工作情况验证了该一般性结论。

Abstract:

Aiming at the negative current phenomenon of three － phase three － wire electric energy meter correctly connected in electricity information acquisition system，the measurement principle and the phasor diagram are used to summarize the laws from the perspective of power factor，and the general conclusion is verified by the nature of the load and the field work．
