ELEKTRISCHE SCHUTZSCHALTEINRICHTUNG

Apparatus sensitive to an electric intensity that includes; A first transformer [figures 1 2, 7 (ct1) figure. 8 (ct4); figure 9 (ct5)] Said transformer including an input winding l1 adapted to be energized from an alternating current network; and an output winding system [figures 2, 7, 8 (ni, n2); figure 9 (900)] that supply a first (i01) and a second (i02) electrical currents, an energized energy storage device 148 said first electric intensity, said second electric intensity having a magnitude determined by the magnitude of the electric current in said alternating current network, and characterized in that it includes a control device [figures 1, 2 (120); figure 7 (700); figure 8 (800); figure 9 (910)] that controls said winding system in such a way that said first and second electric currents are sequentially switched from said winding system of output windings, during a half cycle of the alternating current of the network, for replenish the energy dissipated from the energy storage device during the previous half cycle and to provide a replica of the current from the alternating current network.
