Research on reliability test of dual-core smart electricity meter based on switching power supply of silicon carbide

The dual-core smart electricity meter based on switching power supply of silicon carbide is an important attempt of new technology in the engineering field, especially the power industry. In response to its lack of reliability testing standards, In this paper, according to the existing smart meter operating environment, combined with the characteristics of switching power supply of silicon carbide and the dual-core smart electricity meter, and the various stress analysis of the meter, this paper proposes the reliability detection scheme and corresponding specific methods.The proposed detection scheme is very important to determine the reliability index of the dual-core smart electricity meter based on switching power supply of silicon carbide. In this way, we can improve the technology level of smart power grid and ensure the safe and stable operation of power grid.
