Abstract
An electronic device for monitoring an electrical quantity out of a voltage and arc intensity relative to an alternating current flowing in an electrical conductor, includes a measurement module configured to measure at least one value of the electrical quantity, a wireless transceiver, and a transmission module linked to the wireless transceiver. The monitoring device furthermore includes a computation module configured to compute at least one parameter for monitoring the electrical quantity as a function of at least one measured value of the electrical quantity, each monitoring parameter being chosen from an angular phase of the electrical quantity and a modulus of the electrical quantity, the transmission module being configured to transmit, to another electronic device, a data message containing at least one computed monitoring parameter.
