The insulation fault locators ISOSCAN® EDS440/441 are used in with the ISOMETER® iso685-D-P or the locating current injector PGH to locate insulation faults in unearthed power supply systems (IT systems). The EDS440/441 detect locating current signals generated by the insulation monitoring device iso685-D-P or IRDH575 or the locating current injector PGH. Up to 12 measuring current transformers can be connected to an EDS44x. In total, up to 21 insulation fault locators can be connected via an RS-485 interface (BS bus protocol) and thereby up to 252 outgoing circuits can be monitored.
Applications:
- Insulation fault location in AC, 3AC and DC IT systems
- Main circuits and control circuits in industrial plants and ships
- Diode-decoupled DC IT systems in power plants
- Systems for medical locations
