摘　　要：分析三相不对称负荷情况下,三表法计量三相四线制电路有功功率的计量误差,以及零序阻抗对每相功率计量误差的影响。This essay analyzes the measurement errors in measuring the active power of the three-phase and four-wire circuits in the case of three-phase asymmetric load by using the three-power-table method.Besides,it also analyzes the influence of zero sequence impedance on the measurement errors of the active power of each phase.

关 键 词：不对称负荷 有功功率 计量误差
