摘　　要：介绍了电能计量装置综合误差的概念,着重介绍了互感器合成误差和二次回路压降误差的计算方法,强调指出不能忽视电压互感器二次回路压降引起的电能计量误差,最后介绍了一些减少综合误差的方法。This paper introduces the composition error of the electric energy measurement device and the calculation method for the resultant error of the trandformer and voltage drop error of the secondary circuit, points out the measurement error of electric energy caused by the voltage drop of the voltage trandformer could not be ignored,and also introduces some methods for reducing the composition error.
