System for measuring an electric current and device for detecting an electric current for such a system

Abstract

System for measuring an electric current and device for detecting an electric current for such a system. This description relates to a system (10) for measuring an electric current (I) flowing in an electrically conductive element (2). The system includes a device (15) for generating a magnetic field in the electrically conductive element, comprising a support (53) and an electrically conductive wire (50) rigidly coupled to the support and comprising at least one turn (52) wound around the support, a device for detecting acoustic waves on the surface of the electrically conductive element, and a control and acquisition device (30) comprising a generator (33) configured to provide at least one current pulse in the electrically conductive wire and an acquisition chain for detecting an electrical signal (S) provided by the detection device.
