内相角为60°的三相无功电能计量装置错误接线分析

Analysis about the False Wiring of Three-phase Reactive Watt-hour Counting Mechanism with 60°Phase Angle

论述用"相量图分析法"分析内相角为60°的三相无功电能计量装置正确接线和各种错误接线时无功电能的计算,所得结论对纠正无功电能计量装置错误接线,及避免计量失准提供了理论根据,具有实用意义。

The paper analyzes the calculation for reactive power,which is about the correct wiring and false wirings of three-phase reactive Watt-hour counting mechanism with 60° phase angle by using the vector graph.The conclusions are practical in providing the theory bases for correcting the false wiring of reactive Watt-hour counting mechanism and avoiding the measurement mistakes.
