Abstract
The invention relates to a device for the measurement of an external electrostatic field, for example, for the detection of storms, which includes a first conductive element (1); an amplifier (2)in charge configuration; an electronic control device (3) which has an input (3a) connectable to the output (2b) of the amplifier (2), to receive an output signal (Vs); and a second conductive element (4) located near to the first conductive element (1) to subject it to a compensating electrostatic field created by a compensating signal (Vc) calculated and generated by the electronic control device, to avoid a drift in the output signal (Vs) caused by the integrating character of the configuration of the amplifier. The invention also relates to a system for differential measurement, a system and method for the detection of storms.
