Title (EN) PROCESS AND DEVICE FOR DETECTING THE POSITION OF A FAULT IN AN ELECTRIC CONNECTION
(FR) PROCEDE ET DISPOSITIF DE DETECTION DE LA POSITION D"UN DEFAUT DANS UNE LIAISON ELECTRIQUE
Abstract:
(EN) Directional detection of fault on transport lines of electric power. According to an embodiment for a connection comprising a plurality of lines in parallel provided each, towards their respective ends, with a directional relay, the indications of all these relays are combined in response to the detection of a fault on the connection in order to determine the presence or absence of the fault on the lines considered. Application, particularly, to lines compensated by series capacitors at the start of lines.
(FR) Detection directionnelle de defaut sur lignes de transport d"energie electrique. Selon un mode de realisation pour une liaison comportant plusieurs lignes en parallele pourvues chacune, vers chacune de leurs extremites respectives, d"un relais directionnel, on combine les indications de l"ensemble de ces relais en reponse a la detection d"un defaut sur la liaison pour determiner la presence ou l"absence du defaut sur les lignes considerees. Application notamment aux lignes compensees par des condensateurs serie au depart de ligne.
