Bender UK next generation rail signal power protection system has increased sensitivity for first fault location, keeping the UK’s rail networks moving with compliance with Network Rail’s Insulation Monitoring and Fault Location requirements.

Bender UK’s Rail Signalling Protection System – RS4 – 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 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 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.

Specific bespoke solutions

The RS4 Tier 1 solution is fully retrofittable and compact for utilisation within SIN119 remedial works.  It does not require a 650V or earth reference connection for FSP installations making the Bender Tier 1 solution fully class 2.

Trackside equipment can be fully integrated into existing FSP architecture and the Tier 1 solution offers remote fault location to FSP or cable length, with precise manual fault finding at 100KΩ.

Rapid and Precise Fault Finding

The ability of RS4 to locate faults more precisely means maintenance teams can respond more quickly, enhancing safety and reducing downtime costs.  Bender UK’s RS4 system continually monitors insulation values to show real-time status of the power system. When the insulation value (IR) drops, the system records the fault and puts a test current signal or pulse into the system which is pulled to earth at the point of failure.

Proven history and track record

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.

The RS4 intelligent insulation and earth fault monitoring system is part of the Bender UK range of rail system protection products that includes monitoring of rail switch points heating units and motors, and control voltage network monitoring for railway crossings

Bender UK is a subsidiary of Bender GmbH – a global, independent company established in the 1940s by Walter Bender. The family owned company has 80 offices worldwide, with headquarters and state of the art production facilities in Grunberg, Germany.

Bender is involved in the innovative design and manufacture of quality electrical safety solutions, serving a range of market sectors delivering solutions which identify electrical faults before they become critical.

Cumbrian based Bender UK is responsible for sales, project management, installation and through-life technical support of Bender products in the UK and Ireland.  The Bender UK team work with leading OEMs, consultants, engineers and end-users to deliver solutions which monitor, forewarn and locate developing insulation failure in complex electrical systems.

Bender UK works in key market sectors, to prevent loss of power and shut-down:

Industrial: Residual current monitoring and power quality management devices monitor electrical networks, plant, and buildings to ensure that they are electrically safe. Bender systems provide a continuous health check on electrical systems delivering far-reaching and cost-effective benefits by predicting when and where issues will occur, tracking power usage to identify potential energy savings.

E-Mobility: Bender is a world leader in the application of safety solutions for charge stations and operating systems for hybrid and electric vehicles.  Collaborating with major manufacturers on passenger, transport and commercial vehicle projects, Bender supplies compliant charge station technologies and insulation monitoring for new generation vehicles.

Rail: An approved supplier to Network Rail, Bender UK technology monitors and protects trackside power supplies and signal systems across the UK, identifying and locating electrical faults, anticipating failure to enable predictive and preventive maintenance, keeping rail networks moving.

Oil, Gas and subsea: Effective management of offshore, on-shore and oil and gas infrastructure is facilitated by Bender line insulation monitoring equipment to prevent downtime and loss of production. Bender also collaborates with OEMs on bespoke offshore and sub-sea applications, utilising certified engineers to conduct fault finding analysis, health surveys and commissioning.

Defence: Complex systems on board Royal Navy surface ships and Astute-class submarines are protected by Bender technology to identify and locate earth faults and help prevent electrical failure.

Healthcare: In the UK and Ireland, Bender is market leader in turnkey healthcare solutions, delivering critical care power systems to protect staff and patients from loss of power in hospitals.   Bender also supplies clinical equipment including high performance Merivaara LED surgical lighting and operating tables, infection-reducing touch screen control panels, and clinical services pendants, backed up by 24/7 service, call-out and technical support support to over 400 hospitals.

From off-the-shelf products, to highly customised systems Bender is a supplier of choice to deliver world-class services for critical infrastructure applications.
