This paper analyzes the research status and existing problems of dynamic performance testing technology in electric energy meter, and analyzes the factors that affect the measurement error of the electric energy meter from two aspects of the electric energy meter internal measurement working principle and the influence of external dynamic load operation conditions. Then, this paper gives the OOK dynamic load test excitation signal model, based on this model, presents the laboratory dynamic error test method of the gateway energy meter and the component scheme of the test system, establishes the dynamic error testing system of electric energy meter, and uses this system to test the dynamic error of different types of gateway energy meters. Finally, this paper analyzes the dynamic error measurement data, and points out the problems existing in the dynamic error of gateway energy meter.
