Abstract

In a method of compensating for parasitic capacitances between a resistor (R3) and an electrically conducting screening electrode (4), e.g. in a potential divider arrangement (R3/R4) for measuring a high voltage (UH) having alternating voltage, there is used an additional electrode (5) which extends around the resistor (R3) and has the form of a semi-cylinder produced from a right-angled triangular sheet of electrically conductive material. The part of the current which flows away from the resistor (R3) due to the alternating voltage between the resistor and the screening electrode, or to the parasitic capacitances, is thus prevented. The other part of this current is replaced through a countercurrent of equal magnitude counteracting the current flowing away.
