Abstract
A signal representative of a rectified current supplied by a current sensor is applied to the input of a correction circuit. The form of the input signal of the correction circuit, deformed with respect to the form of a theoretical signal, is corrected so as to reduce the errors of the rms or mean current values. The output signal of the correction circuit is equal to the input signal if the difference between the output signal and the input signal is lower than a limiting value. In the opposite case, the output signal is equal to a variation signal equal to the limiting value. Application to measuring devices and trip relays.
