We have developed standard designs for our clients, setting the bar for what an optimised protection system looks like. We adapt, and provide designs that are tailored to your needs.
We offer the complete service, from deriving the protection settings to preparing the relay setting files. We are familiar with all major relay manufacturers. Utilising our in-house test racks, we are able to test the schemes we are designing, prior to commissioning on-site. We also offer on-site commissioning support.
