An exemplary embodiment relates to a measuring device for measuring a current flowing in a first cable. The measuring device includes a measuring shunt in the form of a plate connected in series with the first cable and associated with a measuring electronic card connected to a data transmission cable. The measuring shunt further includes a measuring portion of resistive alloy coupled to connection portions on either side of the measuring portion. The connection portions are integrally formed with the measuring portion, and the first cable is secured to at least one of the connection portions of the measuring shunt.
