ABSTRACT:
An electrical short-circuit detection device includes a first signal processing module for receiving a signal representative of an electrical current and supplying a first signal representative of the value of the electrical current and a second signal representative of the differential of the electrical current, and a second processing module for receiving the signals and comprising a short-circuit detection module for supplying a detection signal according to a curve overshoot. The second processing module monitors a limit curve overshoot and a ratio between variations of the signals. A short-circuit detection signal is supplied when the ratio exceeds a preset threshold. A circuit breaker incorporates such a device. The process comprises monitoring limit curve overshoot and the ratio between variations of the signals.
