The portable relay rooms are self-contained, fully integrated portable buildings containing several interconnected sub-systems. They can be positioned at the substation or wind-farm site, often near the project completion date and simply cabled up to a single marshalling kiosk.

Once completed at our factory, the individual systems in the enclosure are first extensively tested as self-contained sub-systems, for example the protection scheme itself, then its interaction with the remote ends are simulated before the control elements.
All the systems are finally tested as a fully integrated package by injecting signals at the marshalling kiosk terminals, ensuring all the correct operations are performed and then detecting the outgoing signals at the marshalling point. This rigorous system testing makes sure that the entire system will perform seamlessly as a Plug-and-Play solution when finally positioned on site.
