Surveys, maintenance and upgrades
Signal Power System Health Surveys
Rail signal power survey and verification
Bender UK is an expert in rail signal power monitoring systems. For over two decades we have supported Network Rail in the design and development of state-of-the-art monitoring equipment.
With thousands of systems installed on the UK’s rail network, the earlier generation Bender equipment will eventually fall below current standards. Potential degradation over time can impact the reliability and accuracy of system measurement and data, affecting performance and potentially leading to failure.
More advanced and intelligent solutions, such as the RS4 are available. Upgrades and improvements to the earlier technology can be identified and implemented via a health check, performed by a Bender expert. These health checks identify potential equipment deterioration, test system health and ensure optimum functionality, through the continuation and upgrade of legacy equipment.
Identifying insulation failure
Pinpointing earth faults
The EDS3090 precisely locates feeder earth faults track side. It is designed to pinpoint earth faults to a specific section of cable by detecting the test signal from Bender devices. The handheld kit doesn’t require disconnection of the cable or transformer and simply clamps to the cable to carry out the evaluation, pinpointing fault location. This delivers faster identification minimising disruption to services, reducing costs and system downtime.
Periodic inspection and testing
Test without disconnection
Electrical equipment must be tested on a regular basis for compliance with standards such as BS7671:2018 and in the interests of rail operators. Periodic inspection and testing helps to identify potential risks to safety including fire, deterioration and damage, minimising high repair costs and consequential damage and penalties as a result of poor maintenance. It is also the only way to guarantee optimum configuration and reliability of equipment.
Bender technology enables continuous and remote power monitoring of rail systems. Operators can test systems without disconnection, in line with BS7671:2018 section 651.2, removing the need for power shutdowns. Remote monitoring supports boots off ballast for improved safety on the UK’s rail network.
Upgrading rail signal power systems
Ensuring compliance with NR/L2/SIGELP/27725
Rail operators aim to comply with NR/L2/SIGELP/27725 and improve the safety of the UK rail network, reducing boots on ballast
On some UK rail networks, earlier generation Bender equipment may be installed. In time this will degrade and become less reliable, affecting the accuracy of system measurement and data. To ensure maximum operational ability and performance, Bender can upgrade earlier generation devices easily and quickly.
New generation Bender rail signal power monitoring systems offer a cost-effective continuation for legacy equipment that is compatible with Network Rail communications protocols, including Intelligent Infrastructure. A rail site survey will help support the identification of the appropriate signal power technology upgrades that can easily be performed by Bender or Network Rail engineers.
