三相四线表出现单相负电流原因分析

Analysis of Negative Current in Three-phase and Four-wire Electricity Meter

针对三相四线表接线正确出现单相负电流的情况进行了现场检查与分析,发现单相负电流是低压集中无功补偿装置单相断线导致的。

According to the situation of single-phase negative current in the connection of three-phase four wire meter,it was found that the single-phase negative current was caused by single-phase disconnection of low-voltage centralized reactive power compensation device.
