Retrofitting involves upgrading the existing system to the latest standards and technology with the aim to achieve uninterrupted power supply and reliable, secure power distribution. Retrofitting protection relays reduces maintenance cost, achieves a safer working environment for the personnel, minimizes the damage to the affected equipment and improves performance.

ABB has developed a complete Relay Retrofit Program, which focuses on the smooth and controlled replacement of selected protection relays with modern protection and control devices from the Relion® product family. The program includes all the devices, accessories, hardware and software tools and documentation (manuals) needed for a timely scheduled and controlled execution of retrofit projects. 

ABB also has relay retrofit kits for smooth installation when replacing existing protection relays. These mechanical replacement kits include pre-fabricated plates to ensure compatibility with the mechanical design of the replacement product.
