Abstract
LA DETECTION DE L'ORIENTATION DE DEFAUTS PROCHES DU POSTE DE MESURE EST PROBLEMATIQUE EN RAISON DE LA FAIBLE TENSION DE MESURE, EN PARTICULIER EN CAS DE COURTS-CIRCUITS BIPOLAIRES DANS LESQUELS LA TENSION DE MESUREU APPARAIT SOUS FORME DE DIFFERENCE ENTRE DEUX TENSIONS SIMPLESU, U, LA DIFFERENCE ANGULAIRE DES PHASES ETANT FAIBLE. LES ERREURS DE MESURE ET LA DISPERSION DES RAPPORTS DE TRANSMISSION DES CANAUX DE MESURE RISQUENT DE FALSIFIER LA DETERMINATION DE L'ORIENTATION. LE PROCEDE DE L'INVENTION CONSISTE A INTRODUIRE UN ANGLE SUPPLEMENTAIREA DANS LA RELATION DES PHASES D'AU MOINS L'UNE DES TENSIONS SIMPLESU UTILISEE POUR LA FORMATION DE LA TENSION DE MESURE DU DEFAUTU. AINSI, MEME LORSQUE LA DIFFERENCE ANGULAIRE DES PHASES DES TENSIONS SIMPLESU, U EST FAIBLE, L'AMPLITUDE EST SUFFISANTE ET L'ORIENTATION DE LA TENSION DE MESURE DU DEFAUTU EST BIEN DEFINIE. APPLICATION A LA RECHERCHE DES DEFAUTS DANS LES RESEAUX ELECTRIQUES.
