Bender UK’s RS4 Rail Signal Power Protection delivers multiple-tier smart cable insulation monitoring that Network Rail needs to reduce rail downtime and improve operations. The new RS4 steps up the performance of Bender’s already proven rail signalling protection systems to provide a holistic picture of cable health, along with a rich data set that meets the requirements of standard NR/L2/ SIGELP/27725.
The new system employs tried and trusted Bender measuring technology offering increased sensitivity with improved feeder first fault location from the 20kΩ pre- warning level to 100KΩ and higher, depending on system capacitance.
Bender UK’s advanced intelligent insulation monitoring equipment has a proven track record with more than 1,000 systems installed across the UK’s rail networks over the last two decades. It is an efficient and affordable tool for safeguarding signal power systems and other critical power supplies.
Every day Bender equipment plays a vital role in the predictive maintenance and cost-effective fault- finding that is essential to minimise disruption and aid the smooth running of rail services. New RS4 Tier 3 and Tier 2 solutions are already in trial on several key Network Rail routes in the south of England.
The retrofittable solution can upgrade existing RS2/RS3 installations in minutes without disconnection. It offers cost-effective continuation for legacy equipment that is compatible with existing Intelligent Infrastructure remote condition monitoring through GSM enabled data loggers.
The Tier 2 solution provides full insulation resistance levels of individual feeders with increased system visibility at minimal extra cost over Tier 3 technology, and is fully upgradeable to deliver a Tier 1 solution.
Bender UK’s RS4 Rail Signal Power Protection solution for Tier 1 requirements provides full insulation resistance levels of individual cable subsections and within FSP’s (Functional Supply Points). It also offers the flexibility to deliver tailor-made solutions on a project-by-project basis.
