Abstract
An electrical transformer includes a first winding, called primary, at least one second winding, called secondary, switches, and a current detection system, wherein it comprises at least one metal screen having a connection point linked to a neutral potential of the primary winding or intended to be linked to an electrical ground and placed between the primary winding and the at least one secondary winding, the screen being made of an electrically conductive material having a melting point higher than that of the materials constituting the windings; in that the primary winding comprises an input intended to be linked to an external energy source, the switches are placed at the input of the primary winding so as to be able to isolate the primary winding from the external energy source and in that the current detection system is configured to detect a current at the input of the primary winding or a current at the connection point and to close or open the switches based on the detection of the current, the detection system being differential or thermal.
