Abstract

Den jordfeilbryteren som er foreslått har en totalstrømtransformator (3), en magnetbryter (5) og en hovedbryter (4) med hovedstrømkontaktene (4.2, 4.3) til hovedledningene (1, 2). Ved hjelp av en signalgenerator (14), en strømsensor (15), en pulsgenerator og en elektronisk tidsmåler (20), blir feil- reaksjonsverdien og reaksjonstiden til strømbryteren målt med forhåndsbestemte intervaller, sammenlignet med den for- håndsbestemte grensereaksjonsverdiene og reaksjonstidene, og hvis disse grense- verdien blir overskredet blir det straks avgitt alarm. Under målingene hindrer en låseanordning (12) at hovedstrømkontak- tene (4.2, 4.3) åpner seg og/eller lå- seanordningen (12) er formet slik at når forhåndsbestemte grensereaksjonsverdi og reaksjonstiden er overskredet åpnes hovedbryterne (4.2, 4.3) og kan videre tjene som en gjeninnkoblingssperring, som er det samme som en fail-safe-reaksjon. I tillegg blir reaksjonsverdien til strømkretsbryteren multiplisert med reaksjonstiden og dette produktet, som ikke må overskride en bestemt konstant blir anvendt til automatisk overvåkning.
