Government Solutions and Services

SEL specializes in creating digital products and systems that protect, control, and automate electric power systems. Headquartered in Pullman, Washington, we manufacture our products in the United States and serve customers worldwide.

Our genesis is innovation: SEL was founded by the inventor of the electric power industry’s first digital protective relay.

As a company, our mission is to help ensure prosperity and safety by making electric power safer, more reliable, and more economical for everyone. We grow our business and advance the state of the art in the protection and control of electric power by developing products and solutions that are not only innovative but also the most reliable in the industry.

SEL Government Services has been serving U.S. government customers since 2001.

Marine Power Systems

We design, test, and implement systems that protect and control electric power in marine facilities and aboard U.S. Navy ships of all types.

Our solutions turn shipboard power system design and protection from arcane art into reliable engineering, ensuring that these systems safely and reliably power ships and their sailors to the mission, through the mission, and back home again.

The Industry’s Best Warranty

SEL products come with complete technical support and a ten-year factory warranty—the best in the electric power industry.

This warranty extends not only to factory standard devices, but also to all devices customized by SEL Government Services.

If a product fails under warranty, repair and replacement are free. We service and repair every device we manufacture for its entire service life.
