[edit] History
SEL was founded in Pullman, Washington in 1982 when Dr. Edmund O. Schweitzer III invented and marketed the first all-digital protective relay, reducing the cost and complexity of power protection and revolutionizing the industry. Schweitzer created the relay as a Ph.D. project while at Washington State University. The company shipped its first products to Otter Tail Power Company in Fergus Falls, Minnesota in 1984. In 1985, SEL built its first building and employed eleven people. The company continues to grow and today provides products and services in 132 countries.
