Abstract: A device includes a current difference measurement module for measuring the difference between a current flowing in a positive contact of the electrical installation and a current flowing in a negative contact of the electrical installation, a low-pass filter for filtering the differential current, a full-wave rectifier without threshold module for rectifying the filtered current and a trip module for emitting a trip command when the rectified current is greater than or equal to a predetermined threshold for a predetermined duration. The device thus makes it possible to protect a DC-voltage electrical installation in a noisy environment.

Abstract: An electrical link (290) configured to link a DC high-voltage power source (270) to a user apparatus (250), and includes an electrical conductor (240) surrounded by an insulating cover and an electrical protection device (200) including: a conductive sleeve (280) arranged around the insulating cover, a biasing module (245) configured to voltage-bias the conductive sleeve (280), a circuit breaker (210) arranged on the conductor (240) and configured to cut off a current transiting through the conductor (240), and a detection module (220) connected to the conductive sleeve (280) and configured to detect a current leak out of the conductor (240) and to command the circuit breaker (210) on the basis of the detection. The invention also relates to a method for the secure supply of electric power.
