1. A device for measuring at least one electrical variable of a current intended to flow in an electric apparatus, the electric apparatus comprising at least one connection terminal, each connection terminal being designed to be electrically connected to the end of a corresponding electric conductor, the device comprising at least one current sensor, each current sensor being configured for measuring the current flowing in a corresponding electric conductor,
wherein the device further comprises at least one electrically conductive spacer, each spacer being configured for being interposed between a respective connection terminal and the end of a corresponding electric conductor, and
wherein each current sensor is further positioned around a respective spacer, to measure the current flowing through said spacer, between the electric conductor and the corresponding connection terminal.
