Abstract
A system (10) for measuring an electric current (I) flowing through an electrically conductive element (2) comprises 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 coil (52) wound around the support. The system further comprises a device for detecting (60) 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.
