Electricity meters are divided into single-phase electricity meters and three-phase electricity meters. There are also some special-purpose electricity meters, such as multi-rate electricity meters, maximum demand meters, reactive energy meters, DC electricity meters, standard electricity meters, etc. The electricity meter model is represented by an arrangement of letters and numbers, including category code + group code + design serial number + derivative number. Electricity meters are widely used and can be used to measure the electricity generated by power plants and the electricity consumed by various users, and as a basis for economic accounting and collection of electricity charges.
