This paper describes a calibration device of high voltage capacitance bridge developed by National Institute of Metrology, China (NIM). The capacitance ratios are from 1/1 to 1000/1 with a MPE of ±1×10-5, and dissipation factor (D) values are from 0.00001 to 0.1 with a MPE of ±(0.1%×D+0.00001). A control program was developed by Labview software, which can automatically control the connection of the internal components, switch the measuring point under high voltage (HV).
