The main task of Division of Electricity and Magnetism is to develop and maintain national standards of electrical units. To meet the requirements from industrial and economic development, we provide calibration services and participate in international comparisons. Recent research works focus on watt balance, AC JVS, new type calculable capacitance,high frequency power & energy standard and standard of electrical car charging devices.
