Erdungswiderstands-Überwachung (NGR)
Die Aufgabe eines neutralen Erdungswiderstands ist die Begrenzung des maximalen Fehlerstroms. Dadurch werden mögliche Schäden und Gefahren eines Erdschlusses vermieden. Da das Netz technisch gesehen geerdet ist (daher auch Erdungswiderstand), können Schutzrelais wie gewohnt eingesetzt werden.
Die frühzeitige Erkennung einer Veränderung des Widerstandswertes ermöglicht es, Reparaturen im Vorfeld einzuplanen und auf bislang unerkannte Gefahren hinzuweisen.
Erdungswiderstands-Überwachungsgeräte messen Spannung, Strom und die unterbrechungsfreie Verbindung des neutralen Erdungswiderstands sowie die Spannung von Phase zu Erde. Diese Informationen helfen dabei, Instandhaltungsmaßnahmen zu planen und die Verfügbarkeit des Systems zu verbessern.
