Abstract: Recently, <i style="">dc</i> 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 <i style="">dc</i> 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 <i style="">dc</i> voltage. In-house calibration of HV divider using traceable <i style="">dc</i> 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.
