摘要

Automatic protection device against changing the order of the phases in a distribution network, characterized in that it essentially comprises an interruption relay whose coil is supplied by a phase of the three-phase system and by the average point of attachment of a capacitor and a resistance which are mounted in series and whose ends are connected between the other two phases of the three-phase system itself.
