A presettable voltage sensor includes an electrode faced by an electric field probe and connected to a voltage source; a screening conductive shell wrapping the probe and connected to a reference potential; a dielectric material housed within the shell and interposed between the probe and the electrode; a conditioning circuit connected to an exit of the sensor and having a resistor of resistance Rm interposed between the probe and a second reference potential; and an integrator circuit formed from an RC network and having a resistor of resistance Ri, a capacitor of capacitance Ci, and a loss factor which, at a frequency of interest, is of an order of 10−4.
