| 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. |
