This standard stipulates the technical elements for ordering, acceptance, and use of multifunctional energy meters in the power industry, and also standardizes function settings. This standard applies to installed multi-function electric energy meters (referred to as electric energy meters) that measure single- and three-phase AC electric energy with a reference frequency of 50Hz (or 60Hz). This standard only stipulates the functions that multi-function electric energy meters must have and the technical performance that must be achieved. For the technical requirements of multi-rate electric energy meters, please refer to the relevant content of this standard.
