ISOSCAN® EDS460-D

ISOSCAN® EDS460-D

  • Automatic ground-fault location
  • Application main circuits
  • 12 measuring channels for measuring current transformers
  • CT connection monitoring
  • Universal system concept

The ground-fault locators EDS460/490 in combination with the ISOMETER® IRDH575 or the locating current injector PGH are applied for localizing ground faults in ungrounded systems (IT systems). The locating current signals generated by the ground-fault monitoring device IRDH575 or the locating current injector PGH are detected by measuring current transformers and evaluated by the ground-fault locators. Up to 12 measuring current transformers can be connected to one EDS460/490. A total of 90 EDS ground-fault locators can be connected via one RS-485 interface (BMS protocol). Hence, up to 1080 circuits can be monitored. The maximum scanning time is 10 s, see TGH1394.
