Abstract

Beskyttelsesinnretning for en oscillerende kraftkrets (4) for en minefjerningsspole (6), hvor innretningen omfatter kretsbrytende anordning (2) anbrakt mellom et forsyningsnett (R) med vekselstrøm og kraftkretsen (4), kjennetegnet ved at innretningen omfatter minst en anordning for å måle og analysere strømmen tilført kraftkretsen, anordning for å påvise forekomsten av en likestrøm og koplet til utløsningsanordning (9) som sikrer åpningen av den kretsbrytende anordning (2) når vekselstrømmen opphører.
