RS4 Tier 3

RS4 Tier 3

  • Tier 3 RS4 is the enhanced rail signalling protection system
  • For compliance with NR/L2/SIGELP/27725 Tier 3
  • Improved fault location from 20KΩ to 100KΩ
  • Cost effective and easy to upgrade to legacy equipment
  • Housed in Class II GRP enclosure for lighter and compact design

RS4 Tier 3 is an integrated insulation monitoring and earth fault location system. Utilising proven Bender technology seen in previous variants (RS3), this Tier 3 compliant RS4 is designed to comply with Network Rail standard NR/L2/SIGELP/27725. This innovative, cutting edge technology is available as a new or retrofit solution, to deliver monitoring and protection for railway electrical systems on the UK’s rail infrastructure.

RS4 Tier 3 enables monitoring and fault location with improved accuracy and advanced sensitivity capabilities. The increased sensitivity strengthens fault location from the 20kΩ pre-warning level to 100kΩ.

The Tier 3 system provides overall IR measurements, as well as feeder level fault location. Housed within a Class II GRP enclosure, Tier 3 is lighter and more compact in comparison to the previous RS3 version.

Simple to retrofit and update existing RS3 units, RS4 Tier 3 offers a cost-effective upgrade to legacy equipment that is compatible with existing Intelligent Infrastructure remote condition monitoring through data loggers.
