Abstract

Et system og en fremgangsmåte for å stedfeste feil på kraftsystemoverføringslinjer med flere tilkoplingspunkter ved anvendelse av synkroniserte vektormålinger for nøyaktig å bestemme feilbeliggenhet og feilimpedans uavhengig av feiltype, feilresistans og kopling til andre nærliggende kraftsystemoverføringslinjer.
