METHOD AND DEVICE FOR MEASURING THE DYNAMIC COMPONENTS OF AN ELECTRIC CURRENT IN THE PRESENCE OF A CONTINUOUS COMPONENT

摘要

The method comprises a first step for converting by magnetic coupling the current (I(t)) to be measured into a first induced current (I1(t)), and a second magnetic coupling current conversion step, in which the input current is the induced current from the first conversion step, and the induced current from the second conversion step (Is(t)) is applied to a measurement impedance (8) to provide an image of the dynamic component of the current (I(t)) to be measured.
