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® isoMED427P, are designed for insulation fault location in unearthed power supplies (IT systems). The locating current pulse generated by the ISOMETER® isoMED427P 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).

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.

Features

  • Insulation fault location in AC, AC/DC and DC IT systems
  • 6 measuring channels with measuring current transformer per EDS151
  • Up to 528 measuring channels can be combined by the BMS bus in the IT system being monitored: 88 x 6 measuring channels
  • Response sensitivity EDS151: 0.5 mA
  • A response time of up to 8 s in the AC system acc. to IEC 61557-9
  • RS-485 interface with BMS protocol
  • BMS address range 3…90
  • Cyclical self test

Applications

  • Insulation fault location in AC, AC/DC and DC IT systems
  • DC main circuits in industrial plants, power stations and ships
  • IT systems for medical locations and control circuits
