Abstract
A device for measuring electric currents includes Rogowski-type current sensors, each configured to measure an AC electric current in an electrical conductor, each sensor including coils that are electrically connected in series to form a measurement circuit and being joined to one another to delimit a central zone of this sensor to receive the corresponding electrical conductor. One of the coils is common to the first and second sensors, this common coil being electrically connected to the first and second measurement circuits.
