SEL stands for leadership in price, quality, features, innovation, delivery, and service. We continuously invest in our people and our physical assets to provide new services and products as well as to advance in all areas of business and service to our customers. SEL introduced the world's first digital relay in 1984, revolutionizing the power protection industry by offering fault locating and other features for a fraction of the cost of earlier systems. In the years since, we have grown and developed a complete line of products for the protection, monitoring, control, automation, and metering of electric power systems. With our newly created metering division, we bring SEL quality and innovation into yet another line of products. Our first meter, the SEL-734 Revenue Metering System, leads the industry by providing a complete phasor measurement unit to give system operators a real-time view of the power system state. SEL relays, communications processors, meters, fiber optics, and software products are the roots of complete integrated solutions.
