Voltage sensing device

The invention relates to a voltage sensing device (1) for a high and/or medium voltage power carrying conductor (2), the voltage sensing device comprising: a radially outer electrode (3) operable as a first sensing electrode of a sensing capacitor for sensing the voltage of the power carrying conductor; a radially inner electrode (2, 6) operable as a second sensing electrode of the sensing capacitor; a dielectric material (5) arranged between the inner and the outer electrode (3, 2, 6), wherein the coefficient of thermal expansion of the material of at least one electrode (3, 2, 6) is selected such that it compensates the temperature dependent parameters of the dielectric material (5) and/or the other electrode (3, 2, 6), that influences the capacity of the voltage sensing capacitor.
