Portable device for current measurement using induced magnetic fields

Portable device for a contactless measurement of a current passing through an electrical conductor, the device including a measuring module and a processing module, the measuring module, configured to be held by an operator in contact with the conductor in a plane substantially orthogonal to this conductor and without clamping this conductor, including one or two pluralities of magnetic field sensors, and the processing module being configured to perform a determined linear combination of the plurality of signals delivered by one or the two pluralities of magnetic field sensors, so as to perform an angular spatial filtering isolating the current to be measured from other disturbing currents passing through other conductors.
