【 摘 要 】

At present, the short of calibration of digital energy meter include deficiency of standard, inefficiency, and the lack of proper methods. In this paper, based on four commonly used methods(Watt-second method, standard digital meter method, standard digital power source method, standard analog meter method), the factors that cause the error of these calibration methods are introduced, and relevant measures of improvement and optimization are put forward.
