Abstract

In this paper, a new resistive voltage divider having vertically placed resistors is designed. This resistive voltage divider is supposed to be utilized in laboratory medium voltage measurement in the frequency range from DC to 9 kHz where most of the voltage transducers are failed to accurately function. The simulation results, validated by measurements, show a frequency response where the scale factor and the phase error variation ranges are respectively 2 and 4 times better than the ones required by standard IEC 60044-8:2002. These results take advantage from a plate connected to the low voltage section and a shield separating the HV part from the LV arm of the voltage divider. The maximum scale factor deviation from the rated value is about 2.4% and the maximum phase error is about 22.9 mrad. These promising results have been obtained in a wide frequency range up to 9 kHz, which is quite unusual for resistive dividers.
