摘　　要：电能计量装置差错种类繁多,多年以来,电力营销中的失压电量追补案例大都以理论计算方式来对电量进行追补,但往往由于现场实际情况复杂,可能造成追补电量过高从而产生客户纠纷。根据三相三线电能计量装置差错后的追补电量原则和追补电量的基本原理,着重分析了电压互感器在一次保险熔断后,理论计算和实际测量2方面计算失压电量的不同;探讨电能表失压后产生的相位和幅值都相对稳定的残余电压导致计算追补电量时重复计算电量的情况,以期避免由于此类原因导致的使计算追补电量远大于实际追补电量,减少计量纠纷的发生。Power measurement device error variety,over the years,power marketing in the loss of the piezoelectric volume to make up cases of mostly theoretical ways of power to pursue.However,it is often due to the field situation complex and may result in retroactive power is too high resulting in customer disputes.we will analyzes the voltage transformer in a fuse,which is based on the basic principles of the three-phase three-wire power metering device error,and the theoretical calculation and actual measurement of both computing loss of piezoelectric different amount;of energy meter loss of pressure resulting from the phase and amplitude are relatively stable residual voltage cause the calculation to make up for power when the double counting of electricity situation,in order to avoid such causes the computation to make up for electricity is much larger than the actual make up for electricity and reduce the measurement of the dispute occurred.
