AbstractThe establishment of a DC power meter calibration system using a DC current comparator and a synchronous sampling technique at China Electric Power Research Institute (CEPRI) is described. Measurements can be made at DC voltages ranging from lOmV to IOOOV, and DC currents from lOrnA to SOOA. The system features a synchronous voltage/current sampling system and a multi-ratio DC current comparator. The uncertainty of the DC power meter calibration system is estimated to be not more than 120 JJ.WIW. Furthermore, a comparison of DC power meter calibration systems between CEPRI and National Institute of Metrology China (NIMC) is discussed and presented.
