[0002] An electricity meter, short for energy meter, is an instrument used to measure electrical energy. It is also called a kilowatt-hour meter, fire meter, or simply a kilowatt-hour meter. With the development of power transmission technology, more and more mechanical and electronic electricity meters are widely used in industrial production. The input terminal of an electricity meter is connected to the power grid, either near or far. When the power grid fails or is struck by lightning, surge voltages or overvoltages can easily occur in the transmission lines. Overvoltages affect the linear stability of the meter's measurement error and may even cause the meter to malfunction. Therefore, overvoltage protection for electricity meters is particularly important. Thus, electricity meters are usually placed in meter boxes for protection.
