Abstract: Recently, dc high voltage laboratory has been established at National Physical Laboratory, India (NPLI) for calibration of high voltage (HV) equipment. High Voltage resistive divider is the heart of dc high voltage measurements. The traceability of HV measurements is directly related to divider’s traceability to Josphson voltage standard, which is the primary standard of dc voltage. In-house calibration of HV divider using traceable dc calibrator and 10 V reference standard has been discussed in the present paper. The overall uncertainty of measurement has also been calculated and is about 10 ppm.
