Abstract
Device for limiting disturbances of an electrical nature, such as currents induced by overvoltages caused by these disturbances, in particular electromagnetic, for example relating to events of lightning type in an electrical installation, comprising at least one protection apparatus of isolator or differential breaker type intended to protect at least one downstream electrical installation having at least one load and being powered between a neutral conductor (3) and at least one phase conductor (5) and comprising an earth link. This device is characterized in that it comprises a common-mode low-pass filter (4) connected in parallel between the neutral and each phase on one hand, and earth on the other hand.
Claims24
A device for limiting disturbances or disruptions of an electrical nature, comprising:
- at least one breaker type or differential switch type protective device configured to protect a downstream electric circuit having a load and being supplied by a neutral conductor, a phase conductor, and a grounding link;
- and
- a common mode low-pass filter connected in parallel between the neutral conductor and each of the phase conductor on the one hand and the grounding link on the other hand.
