DEVICE AND SYSTEM FOR MEASURING AN EXTERNAL ELECTROSTATIC FIELD, AND SYSTEM AND METHOD FOR DETECTING STORMS

摘要

The invention relates to a device for the measurement of an external electrostatic field, for example, for the detection of storms, which comprises:
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, and a system and method for the detection of storms.
