[0003] Transformers are essential equipment for power supply, and the amount of electricity used is measured through fixed energy metering devices. In high-voltage power supply systems, when the total capacity of the transformer is 630kVA or less, electricity can be measured on the low-voltage side, which is called high supply and low metering; that is, from high-voltage power supply to users, the electric energy metering device is installed on the low-voltage side of the user's power transformer to implement low-voltage metering; the loss of the power transformer is in front of the metering device and is not included in the metering data.

[0004] In the high supply and low metering, the metering device is installed on the secondary side of the transformer, which consists of a transformer and an electric energy meter. The measured voltage can be directly connected to the electric energy meter, and the measured current needs to be converted into a 5A standard signal through a current transformer and connected to the electric energy meter to achieve electric energy measurement. In the existing metering devices, due to the different sizes of transformers from different manufacturers, it will bring installation inconveniences during installation; the performance of the metering device is directly related to the accuracy of electric energy measurement. If the metering device is not installed properly, there will be electricity theft. Utility Model Content
