Abstract

En anordning som i et elkraftanlegg er beregnet for å beskytte objekter (l, 7, 27) som er tilkoplet til et elkraft- nett (3) eller annen i elkraftanlegget inngående utrustning, mot feilrelaterte overstrømmer. Til en ledning -(2) som forbinder nettet/utrustningen (3) og objektet (l, 7, 27), er det tilkoplet en overstrømsreduserende innretning (5) som er aktiverbar for overstrømsreduksjon med bistand av en innretning som detek- terer overstrømsbetingelser.
