Being smart about the future of rail
Between the drive towards smart cities, new high speed rail links and increased rail travel across the UK, the pressure is on to make sure our railways can keep up. Progress is not without its challenges, and as the world struggles to balance being more connected there is a real risk that power quality could be affected.

Testing is the key

To help national rail operators, we’ve developed the REOLAB, which is a range of high voltage variable power supplies designed to test static converters used in the production of auxiliary power supplies for onboard power. High power frequency converters are a vital component in supporting the evolution of rail technology, particularly as we become smarter and power towards higher speed trains. To ensure efficiency and safety, these converters have to be tested so that power quality is not adversely affected.

The REOLAB high voltage variable power supplies are designed to test static converters used in the production of auxiliary power supplies for on-board power.

As REOLAB can simulate three-phase mains power it is the ideal tool to test static converters in research and development (R&D) proving grounds, for regular maintenance, in end-of-line products and during production. The ability to manipulate voltage is the key to any good power supply, especially in countries where national energy grids can be unreliable and sometimes outright dangerous. To combat this, REOLAB is designed with a built in soft-start, capable of slowly and gradually bringing the power up to level.


All change

The world of train travel will have to advance at a phenomenal rate to keep up with the move to smart cities. With increasing connectivity across smart cities and projects such as the UK's high speed HS2 network in the pipeline, it's not difficult to envisage the increasing role testing and safety will play a few years down the line. However, with adequate consideration of a sustainable development infrastructure we can meet and exceed our expectations for the future of rail travel.
