ABB has developed a complete Relay Retrofit Program, which focuses on the smooth and controlled replacement of existing protection relays with modern protection and control IEDs. 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. The various phases of the retrofit project can be accurately scheduled and timely executed to minimize downtime of the production or power distribution processes. Further, the Relay Retrofit Program can be used to improve the protection system by implementing new functionality, such as arc fault protection, and by enhancing the horizontal and vertical transfer of information.
A carefully planned and smoothly implemented retrofit program generates added value, and the extended equipment life cycle grants time for forthcoming decision making. The program is based on the use of IEDs from the Relion® product family as replacement devices, on pre-designed installation accessories - and on the use of a dedicated migration tool.
