Abstract
A device for measuring electric currents includes multiple current sensors of Rogowski type, each suitable for measuring an electric current flowing through an electrical conductor, these current sensors being in adjacent pairs and each including coils for measuring the current and a central aperture for receiving the corresponding electrical conductor. Each current sensor includes two of the coils, which coils are positioned in parallel and facing one another on opposite edges of the central aperture and two ferromagnetic bars extending between ends of the coils, perpendicularly to a longitudinal axis of the coils.
