Abstract
Description
technical field
[0001] The invention belongs to the field of intelligent device detection, and in particular relates to a method for evaluating the operating state of an intelligent electric energy meter. Background technique
[0002] As the terminal equipment of the smart grid, the smart energy meter plays an important role in the construction of the smart grid. At present, the State Grid Corporation of China requires that the design life of smart energy meters is not less than 10 years, while the verification regulations for electronic AC energy meters stipulate that the verification period of level 1 and level 2 meters shall not exceed 8 years, and the smart energy meters that have been used for 8 years need It costs a lot to disassemble and send it back to the laboratory for testing. Even if it passes the test, there are only 2 years of life left. Therefore, at present, qualified smart energy meters are often scrapped, resulting in serious waste. In order to solve this...
