摘　　要：论述了用“向量图分析法”分析跨相(90°-φ)三相四线无功电能表正确接线和各种误接线时无功电能的计算,所得结论对纠正无功电能表错误接线,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 meter with striding-phase (90°-φ) by using the vectorgraph. The conclusions are practical,it supply the theory bases for correcting the false wiring of reactive Watt-hour meter and avoiding the measurement mistakes.
