摘要

"METHOD FOR DETECTING AN ELECTRIC ARC FORMATION AT LEAST ONE ELECTRIC CABLE AND DEVICE FOR DETECTING AN ELECTRIC ARC FORMATION AT LEAST ONE ELECTRIC CABLE" The invention relates to a detection device (1) database (10) including a plurality of entitlement classes, of which a first class relates to a corona phase and an array (5) comprising means for measuring electrical current and electrical voltage in an electrical cable (2), means for filtering said measurements, and means for digitizing the filtered measurements and forming two digitized data segments, as well as a set (8) comprising means for subjecting each of the two segments to a number of functions to constitute a shape vector, means for determining the ownership class of said shape vector using database (10), and means for deducing from there the presence or absence of a phenomenon not electric arc.
