Abstract

The invention relates to a voltage sensing device for a high and/or medium-voltage power-carrying conductor, the voltages sensing device comprising: • a carrier element (3) with a passageway for receiving the power-carrying conductor, • wherein the carrier element comprises an electrode (4) extending in an axial direction of the passageway of the carrier element and operable as a first electrode of the voltage sensing device, wherein • a conductor (1) of the power cable is operable as the second electrode of the voltage sensing device and wherein • the carrier element has a coefficient of thermal expansion that is less than 5×10^−6 1/K at 20 C.
