“…The display is calibrated in both high voltage and low voltage modes in order to obtain a corrected scale factor that is used in the 200 kV measurement system, according to the following steps: The display of a traceable 100 kV high voltage measurement system (Phenix-kVM100) is calibrated as presented in Abdel Mageed et al. 9 The AC/DC peak voltmeter (MU17) is calibrated in its high voltage mode compared to the display of the traceable Phenix. The low voltage mode is calibrated via a traceable calibrator (Fluke 5720A) to acquire its corresponding low voltage readings. Hence, corrected scale factors are obtained in DC and AC modes and then applied to the 200 kV display. High voltage values up to 200 kV are calculated by multiplying low voltage readings by the corresponding scale factors. …”

This paper focuses on achieving traceability of high voltage measurements up to 200 kV at the Egyptian National Institute of Standards. The measurement system consists of an AC/DC voltmeter and a universal resistive/capacitive high voltage divider. The voltmeter shows measured voltage values based on the scale factor of the voltage divider. The divider ensures a stable capacitance for AC voltage measurements and an additional resistive parallel path for DC voltage measurements. Both the divider and the voltmeter are calibrated in AC and DC modes. All uncertainty components are taken into account to obtain measured values with an acceptable accuracy. The calibration results in traceability to the national standards, which make measurements using the international system of units. The proposed calibration method is useful for the theory and practice of high voltage measurements in education, industrial applications, and electrical metrology studies.
