Abstract
Η παρούσα εφεύρεση σχετίζεται με μέθοδο και διάταξη για την παρακολούθηση σφαλμάτων μόνωσης μεταξύ διαύλου συνεχούς ρεύματος (DC) και γείωσης ή προστατευτικού μεταλλικού περιβλήματος. Η μέθοδος βασίζεται στην αρχή της διαδοχικής σύνδεσης δύο διαφορετικών ηλεκτρικών δικτύων σε πηγή DC (1), στη μέτρηση τουλάχιστον δύο τιμών (V1', V2'), μίας τιμής που σχετίζεται με κάθε δίκτυο, στον υπολογισμό τιμών αντίστασης (R1, R2) που αντιπροσωπεύουν την ποιότητα της μόνωσης, στη σύγκριση των εν λόγω τιμών με επίπεδα συναγερμού, και στη λήψη δράσης συναγερμού, συγκεκριμένα την αποσύνδεση της πηγής (1), εάν επιτευχθούν αυτά τα επίπεδα συναγερμού. Η εφεύρεση σχετίζεται εξίσου με διάταξη για εκτέλεση της μεθόδου, με την εν λόγω διάταξη να περιλαμβάνει διακόπτη (6). Και οι δύο συνθήκες "ανοικτό" ή "κλειστό" αντιστοιχούν σε ένα από τα δύο ηλεκτρικά δίκτυα που συνδέονται στην πηγή (1).
