Abstract
A device for acoustic detection of an electric arc, including a tubular probe suitable for being arranged next to a piece of electrical equipment on which an electric arc is likely to form. An interior space, circumscribed by a wall of the probe, extends along the length of the probe. This interior space is filled with a fluid and acoustically isolated from external noise by the wall. The probe includes, at the periphery of its interior space, on its wall, at least one vulnerable zone suitable for degrading under the effect of the electric arc, revealing a passage to the interior space for an acoustic wave generated by the electric arc. The device further includes at least one acoustic sensor suitable for detecting the acoustic wave that travelled through the passage and propagated in the interior space of the probe.
