ISOSCAN® EDS490-L
- Geautomatiseerde isolatiefout lokalisatie tijdens het in bedrijf zijn van de installatie
- Applicatie hoofdstroomcircuits
- 12 meetkanalen voor meetspoelen, per kanaal een alarmcontact
- Meetspoel aankoppel-controle
- Universeel systeemconcept
Het aardfoutzoeksysteem, voor lokalisatie van isolatiefouten, EDS460/490 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 EDS460/490 kunnen maximaal 12 meetspoelen worden aangesloten. In totaal kunnen maximaal 90 stuks EDS460/490 via een RS-485-interface (BMS-protocol) worden verbonden, zodat maximaal 1080 uitgangen worden bewaakt. De opvraagtijd voor alle meetkanalen is max. 10 s.
