LINE CARRIER CURRENT FILTERING SYSTEM INCLUDING AUTOMATIC FAILURE DETECTION.

摘要

The subject of the invention is a filtration system allowing the attenuation of the frequencies of carrier currents in line, on an alternating current distribution point having a phase (P) and a neutral (N), this system comprising a filter of the type LC comprising an induction (L) arranged in series and a capacity (C) arranged in parallel, this system being remarkable in that it comprises a cut-off device (10) for the connection of the capacity (C) which switches it off in the event of failure of this capacity (C), and an automatic detection device of this cut.
