Analysis of metering misalignment caused by abnormal current of smart energy meter

In addition, when the primary metering current transformer is running, the secondary circuit contact is poor, which causes the smart energy meter to lose current, resulting in abnormal electricity. Analyze the change rule of the metering data of the smart energy meter during the operation of the metering device, calculate the recharge power during the bad contact of the secondary circuit of the current transformer, and propose measures to strengthen the installation quality management, weekly inspection management and remote inspection management of the power metering device to prevent it, so as to ensure the safe, accurate and reliable operation of the power metering device.
