三相三线误接线对计量的影响

The Impact of Three-phase Three-line Wiring Errors on the Measurement

在新装计量装置中由于电流互感器相序、极性的错误导致电能表的误接线,造成电能计量的不准确。列举了几种三相三线电能表常见的误接线,通过向量分析推导出电能表误接线时所反映的有功、无功功率表达式。

In the new metering device, the current transformer phase sequence errors and polarity errors led to the mistaken Meter wiring, and electrical energy measurement inaccurate. This paper lists several three -phase three -line Meter common wiring errors, analysis by vector derived the expression of active and reactive power when Meter wiring error r, which sought to obtain the impact on measurement.
