    Abstract: A protection system configured to protect plural DC voltage sources configured to be connected in parallel between first and second input terminals of a voltage inverter. The voltage inverter can convert a DC input voltage into an AC output voltage. Each DC voltage source is connected by a first electrical conductor to the first input terminal and by a second electrical conductor to the second input terminal. The protection system includes: for each DC voltage source, a first cut-off member and first detector of a defect of isolation of the first conductor with respect to an electrical ground, the first detector and associated first cut-off member connected in series between the corresponding DC voltage source and the first input terminal of the inverter; and a mechanism triggering, in event of detection of the isolation defect, the associated first cut-off member to open the electrical link corresponding to the first conductor.

    Abstract: In this method, the voltage outage load-side is an opening of the circuit breaker, and the circuit breaker is able to interrupt the flow of electric current in an electric connection including an electric conductor. The auxiliary unit comprises a current sensor for measuring the intensity of the current flowing in the electric conductor and a first detection means for detecting the voltage outage load-side from the circuit breaker. The method comprises the following steps: measuring the intensity of the current flowing in the electric conductor, detecting the voltage outage load-side from the electric circuit breaker, determining a cause of the detected voltage outage load-side from the circuit breaker, said cause being selected from the group consisting in: an electric overload, a short-circuit and a voltage drop.

    Abstract: A differential protection device is designed for an electric disconnecting apparatus, the disconnecting apparatus comprising at least one fixed contact suitable for being connected to a corresponding electrical conductor, at least one movable contact, between a closed position, the movable contact being electrically connected to the corresponding fixed contact in the closed position and electrically isolated from the corresponding fixed contact in an open position, and an actuator for activating opening of the movable contacts when a differential fault is detected. The differential protection device comprises a controller for controlling the actuator. The differential protection device further comprises measuring circuitry for measuring an electrical variable associated with the controller and inhibiting circuitry for inhibiting the controller when the measured electrical variable satisfies a predetermined criterion.
