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: A module for detecting an electrical fault includes a housing; a first conductor and a second conductor; a first measurement toroid, positioned around the first conductor and around the second conductor, for measuring a differential current flowing between the first and second conductors; a second measurement toroid, positioned around the first conductor, for detecting an electric arc signal flowing through this conductor; a relay; an electronic processing circuit configured to switch the relay according to the current measured by the measurement toroids. The measurement toroids are aligned with one another and the first toroid takes the shape of an elongated tube and allows the differential protection to operate with its own current.

Abstract: An electric arc detection device samples first, second and third filterings of a signal in a current window and in another window. A correlation is determined between first filtering samples of the current and the other window, a correlation is determined between second filtering samples of the current and the other window, and a correlation is determined between third filtering samples of the current window and the other window. An arc is then detected as a function of the correlations.
