Abstract In view of the calculation for makeup electricity of three-phase and three-wire electricity meter when A-phase or C-phase fuse is blown, a new method for calculating makeup electricity is proposed to obtain the actual active power by using the power data of the non-loss-voltage phase metering element, and obtain the actual electric quantity by summing the power. Combined with the actual situation, this method can effectively avoid the influence of the residual voltage of the voltage-loss phase, improve the reliability and accuracy of the calculation of the supplementary power, and provide a feasible method for solving the calculation problem of the supplementary power.
