Evaluation of The Performance of Portable New Design High DC Voltage Measuring System up 40 kV

Portable DC high voltage (HV) measuring system up to 40 kV has been designed and built with DC HV probe and AC/DC voltmeter developed at TUBITAK UME (The Scientific and Technological Research Council of Turkey). The structure and construction of the HV probe and DC voltmeter for evaluating their performance are described. The comparison measurements have been done using the reference DC HV system up to 40 kV. The voltmeter described here was developed for using in the measurement or calibration of DC HVs with high input impedance greater than 100 MΩ. The voltage error obtained in comparison measurements is less than 100 μV/V at 40 kV.
