摘要(Abstract)：

随着电子式电能表在电能计量中的广泛应用,有必要探讨外来磁场对电子式电能表的影响。通过强磁铁干扰电子式电能表的试验,分析了恒定磁场对电子式电能表的影响,并在此基础上对电子式电能表提出了改进措施,从而保证电子式电能表在强磁场的影响下也能准确计量。
Electronic energy meter is widely used in electric power system, so jockeys need to discuss the impact of external magnetic field on electronic energy meter. According to the test about strong magnet interfering electronic energy meter, we analyse the impact of magnetic field on electronic energy meter in this paper, and give some amelioration suggestion. Thus the electronic energy meter can measure accurately under the impact of magnet.
