Abstract

Anordning for å evaluere linjetester for en utgående kraftlinje, omfattende en samleskinne (3) for å mate en vekselspenning til en kontaktledning (5) tilkoblet samleskinnen via en hovedbryter (9), og et utstyr (1) for å testenergisere kraftlinjen, hvilket testutstyr omfatter en testmotstand (2) som er tilkoblet mellom samleskinnen og kontaktledningen (7) for å energisere testmotstanden med vekselspenningen fra samleskinnen. Anordningen er innrettet til å registrere spenningen mellom kontaktledningen (5) og jord under testenergisering og til å bestemme minst én egenskap for formen på spenningskurven basert på den registrerte spenningen og å bestemme om kraftlinjen er kortsluttet eller ikke basert på den bestemte karakteristikken.
