摘　　要：采用传统的电能表现场校验方法时,现场运行的电能表按用户负荷大小划分,定期现场校验,其缺点是现场校验周期长,难以实时监测电能表的实际(变化的)负荷。因此提出了一种电能表远程在线不停电校验方法,可以对有问题的电能表进行校验并发出报警信息,确定最佳校验时间,从而让电能表远程在线校验运维管理真正实现“当检即检”,形成良好的管理机制。When the traditional on-site calibration method is adopted,the on-site operation of the watt hour meter is divided according to the user's load,and the on-site calibration is carried out regularly.The disadvantage is that the on-site calibration cycle is long,and it is difficult to monitor the actual(changing)load of the watt hour meter in real time.Therefore,a remote on-line non power outage verification method of watt hour meter was proposed,which could verify the faulty watt hour meter and send out alarm information to determine the best verification time,so as to make the operation and maintenance management of remote on-line verification of watt hour meter truly realize"inspection on time"and form a good management mechanism.
