1S24 IEC61850 Arc Fault Monitor

Arc fault protection is a relatively new technique employed for the clearance of arcing faults on low voltage panels, MCC’s, BUS bars and within metal clad switchgear and associated cable boxes. Conventional current based protection techniques are at times challenged by the nature of arcing faults, and can result in slow protection clearance times. Slow protection clearance times increase the risk to nearby personnel and increase the degree of damage to plant and equipment. By employing an optical detection technique, Arc Fault Protection results in fast clearance of arcing faults. With the added benefit of IEC61850 Goose Messaging, the 1S24 is a scalable solution capable of being employed in the most challenging applications with reduced engineering overhead. With the flexibility of the IEC 61850 standard ARC tripping with current checking or ARC tripping with operational interlocks are able to be implemented with ease.


  • Up to 16 arc fault sensors
  • Up to 16 independent arc fault SARC logic nodes
  • Arc fault signaling via Ethernet IEC61850 GOOSE messaging
  • 10Base-T / 100Base-TX port
  • Optional 100Base-FX port
  • Trip indication LED for each arc fault sensor
  • Continuous arc sensor supervision with sensor fail LED for each zone
  • Non volatile memory ensures last recorded alarm states are restored on power up
  • High speed arc fault tripping duty output contacts < 10ms
  • System configuration via web browser
  • Wide range status input to block arc fault tripping
  • Front panel reset button and status input
  • Self supervision watchdog with healthy LED and alarm contact
  • Wide range auxiliary supply
  • Made in Australia





The 1S24.cid can be used as-is on the 1S24 and has a default set of 16 separate Goose messages, one for each FADet point with stVal and Quality included in the Goose.
However, The IP address within this file, must match the IP address configured on the 1S24.

The 1S24-bare.icd has an ICD extension as it is intended for importing into site configuration tools which can add specific Goose to it (with whatever VLAN, Versioning etc. required). The Tool can then export a CID file for use on the 1S24. On the 1S24 itself, it must be called 1S24.cid.
