Case Studies


Client: Railway


UPS/PSP supply in preparation of Olympic Games


NORTH LONDON, United Kingdom

Year: 2011-2012

This re-signalling upgrading project was undertaken to improve passenger/train capacity across North London in readyness for the increased passenger numbers of spectators attending the 2012 London Olympics.

Devontech’s involvment was to provide a supply changeover UPS supported containerised Principal Supply Point at Willesden at the westerly end of the project, a DNO/automatic mains failure generator UPS supported containerised Principal Supply Point at Kentish Town, another supply changeover UPS supported containerised Principal Supply Point at Highbury station and at Stratford Station a UPS Auto Bypass System.

At the easterly end of the project at Upminster Control Center Devontech provided a containerised 500kva automatic mains failure generator complete with a 72 hour full load fuel tank ensuring the Control Center was fully operational during a mains failure and providing a synchronised mains restoration.

The generator supplied both the Control Center enviroment management and all signal loads of system.

All sustained loads were supported by a UPS hot standby system (the output of UPS No1 provides the reserve supply of UPS No2). Each UPS could be automaticaly or manually bypassed.

Together with Atkins Rail Devontech delivered the project within a very tight schedule on time and within budget.

Feltham & Wokingham Re-Signalling Project

– Phase Two 2021

Devontech has recently begun the Phase Two Installation for the client, Atkins to revamp the signal terminals and units based at Feltham & Wokingham. Devontech is proud to show the work below which has been done in relation to this project. These units are constructed from the ground up and benefit from the combined skill and engineering resources of Addicott Electrics Ltd and Devontech Ltd.

This Principal Supply Point or P.S.P as it is known, benefits from a re-enforced damp, soundproof and sealed container based structure which fitted with modules that allow the signalling systems to be managed and controlled with ease in terms of power supply backup. Notice the labelled switch structures on the panels marked in yellow for clear identification. Devontech’s vision proposes that operational elements must be clearly marked so that commissioning to a client is seamless and effortless once operations begin. The black cabinets are manufactured and completed with a paint texture that prevents the ingress of rust in testing environments. The floors are coated with a permanent protective solution that allows cleaning to be maintained whilst the unit is based in rough conditions. As a whole, the unit is sound proof and allows secure access to authorized operators.
