Electrical control and protection device The invention relates to an electrical control and protection device (10) of a set (2, 3) of electrical conductor(s), comprising: - means for measuring the voltage or current (17, 18) in at least one conductor; a processing means (12), suitable for detecting an electric arc in the conductors based on measurements done by said measuring means and, if an electric arc is detected, generating an activation signal (TRIP) and transmitting it to an electric switching device (14) suitable for stopping the flow of the electric current in at least said conductor; said processing means being suitable for further detecting, based at least on some of said voltage or current measurements, at least one malfunction from among a short circuit, an electric current overload, an overvoltage, an undervoltage and a residual current relative to at least said conductor. |
