SYSTEM FOR FILTERING POWERLINE COMMUNICATIONS COMPRISING AUTOMATIC FAULT DETECTION

摘要

The subject of the invention is a filtration system for attenuating carrier line frequencies on an AC 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 capacitor (C) arranged in parallel, this system being remarkable in that it comprises a device (10) for breaking the connection of the capacitor (C) which switches it off in case of failure of this capacity (C), and a device for automatic detection of this cut.
