[0002] At present, electric energy metering devices include various types of electric energy meters, such as transformer ratio testers, current transformer ratio testers, etc. The production of electric power and other products is different, and its characteristics are that the three departments of generation, supply and use are connected into a system, which cannot be interrupted and completed at the same time, and are closely related to each other. How to sell and how to calculate the economy between them requires a measuring instrument to measure and calculate the amount of electric energy between the three departments, which is the electric energy metering device.
