Generation

Advanced measurement, security, and control features are built into every SEL product to ensure that generators are protected, properly metered, and connected to the grid without interruption.

Generation hero

When SEL introduced the world’s first digital protective relay in 1984, we revolutionized the safety, economy, and reliability of electric power. Since then, we’ve grown to become a global leader in the industry—and it’s still our goal to provide the world’s most reliable solutions for the protection and control of electric power.

An SEL solution for your generation facilities will pay off in higher reliability and a lower lifetime cost of ownership—plus the security of an investment that is protected by the industry’s best warranty and support.

Microgrid Solution Plays Big on Campus

An SEL control system synchronizes Montclair State University’s 5.4 MW CHCP plant with on-campus loads and the regional grid. This system also allows the university to operate as a true microgrid—islanding its generation, shedding load intelligently, and seamlessly reconnecting as needed.
