Abstract
A method includes detecting any light beam from 300 nm to 430 nm within the distribution system and, when this beam is detected, generating a signal indicating the presence of an internal arc inside the system; analyzing the characteristics of the light beam based on the signal and, if these characteristics meet required conditions for characterizing an internal arc fault, sending an internal arc fault signal, then; in the presence of an internal arc fault, attenuating its effects in the distribution system. Between the detecting and the analyzing, the visible and infrared portions of this beam are removed, these portions being likely to arise from ionized gases ejected by outlets of a low-voltage circuit breaker interrupting a short-circuit current. A protection device for carrying out this method includes a light detector associated with current-measuring sensors, and protection means including a main circuit breaker, a short-circuiter and a relay.
