ISOSCAN® EDS151

ISOSCAN® EDS151

  • Automatic insulation fault location
  • Application control circuits
  • 6 measuring channels
  • Integrated measuring current transformers
  • Universal system concept

The insulation fault locator EDS151 in conjunction with the ISOMETER® IRDH575 or the locating current injector PGH, are designed for insulation fault location in unearthed power supplies (IT systems). The locating current pulse generated by the ISOMETER® IRDH575 or the locating current injector PGH are detected using the integrated measuring current transformers and evaluated by the insulation fault locators. The integration of six measuring current transformers in an EDS151 permits all current-carrying conductors of an outgoing line to be routed through. The response time for an alarm message inclusively indication on the respective display device is max. 8 s (e.g. MK2430/MK800).

A total of 88 EDS151 devices can be connected via an RS-485 interface (BMS protocol). Hence, up to 528 circuits can be monitored. Activities on the BMS bus are indicated by an alarm LED.
