Electricity is something many of us take for granted. But without electricity the lights go out, computers shut down and fridges, TV sets, and air-conditioning stop working. And so do factories, data centers and hospitals. To prevent this from happening more than one million protection and control relays from ABB supervise electricity distribution networks in over 100 countries, enabling the safe and reliable distribution of electric power.

The main purpose of protection relays is to observe the electrical grid and make protection decisions autonomously so that flow of electricity passes safely through the distribution network.

ABB’s smart protection technology ensures smooth and safe everyday life without blackouts. ABB released its first programmable relays based on the use of microprocessors in 1985. ABB’s Relion® protection and control family of relays are being used in industries of all kind, keeping the flow of electrons stable.

The growing integration of renewable and distributed energy resources, as well as the increasing consumption of electricity, is leading to significant changes in electricity networks. Products from ABB like the REX640 keep the electrical distribution network safe and stable, supporting an environmentally more sustainable lifestyle.

ABB is truly helping to keep the lights on, as well as motors and all electric equipment humming.
