Abstract

En feilstrøms-sensorkopling er uavhengig av hjelpe- spenning, og overskridelse av en øvre grenseverdi av feil- strømmen blir meldt ved en halvleder-bryter og denne meldingen blir ved underskridelse av en nedre grenseverdi utløst igjen selvstendig. Koplingen omfatter en balansert transformator til oppfattelse av feilstrømmen, og minst ei sekundærvikling, som er tilkoplet til bryter-elektronikk. Dermed blir forsyningsspenning til elektronikken hentet fra en spenning som er indusert av feilstrømmen i minst den ene sekundærvikl ingen.
