Electrical current measurement module

A current measurement module intended to measure an electrical current passing through an electrical conductor, the module comprising a main winding of electrically conductive wire,

• wherein the current measurement module further comprises a ferromagnetic element of dished form, the ferromagnetic element comprising a rounded central portion and two arms of a same length extending on either side of the rounded central portion, the ferromagnetic element having an axis of symmetry parallel to each of the arms, the main winding extending in a direction at right angles to said axis of symmetry, and being disposed between said arms of the ferromagnetic element, so as to form a through-housing adapted to surround said electrical conductor, the current measurement module being configured to be opened into two parts by separating the ferromagnetic element from the main winding, a first part comprising at least the main winding and a second part comprising at least the rounded central portion of the ferromagnetic element, wherein separation of the ferromagnetic element from the main winding allows insertion of said electrical conductor between the two parts.
