ISOSCAN® EDS460-DG
Het aardfoutzoeksysteem, voor lokalisatie van isolatiefouten, EDS461/491 wordt in combinatie met de ISOMETER® IRDH575 of de testpulsgenerator PGH gebruikt voor het lokaliseren van isolatiefouten in ongeaarde netstelsels (IT-systemen). Daartoe registreren ze met meetspoelen de testpulssignalen die door het isolatiebewakingsapparaat IRDH575 of de testpulsgenerator PGH worden gegenereerd.
Op een EDS461/491 kunnen maximaal 12 meetspoelen worden aangesloten. In totaal kunnen maximaal 90 stuks EDS461/491 via een RS-485-interface (BMS-protocol) worden verbonden, zodat maximaal 1080 uitgangen worden bewaakt. De opvraagtijd voor alle meetkanalen is max. 10 s. (zieTGH1394).
Deze uitvoering is speciaal geschikt voor netwerken met hoge netontladingscapaciteiten (20.000 µFV, zie de karakteristieken bij de technische gegevens).
