Power Management


SEL powerMAX Power Management and Control Systems are specifically engineered for industries with critical processes that need to stay online.

Prevent widespread blackouts and keep your critical processes running with advanced high-speed protection and control technology. Achieve total system awareness with time-synchronized condition-monitoring systems that track equipment status, electrical metering, cyber attacks, network traffic, and more. Improve human safety and reduce equipment damage with adaptive protection, advanced protection systems, and arc-flash mitigation.

powerMAX power management solutions also seamlessly integrate with our motor protection and management systems to protect your entire facility, from bulk power systems to end devices.

The many applications of powerMAX power management solutions include:

  • Load-shedding systems.
  • Steam controls.
  • Generation-shedding and runback systems.
  • Autosynchronization systems.
  • Fast decoupling solutions.
  • Generation control systems.
  • Cybersecurity.
  • Synchrophasor monitoring and control.

Reliability Is Built In

SEL leverages the time-proven strengths of a relay-based power system architecture and our products’ unmatched reliability to create resilient and efficient electric power management and control systems.

By designing for reliability first, we reduce operations costs, improve system performance, and deliver an unbeatable lifetime return on investment for our customers.

Your operators and engineers are invited to be part of our factory acceptance test and put the system through its paces in our Real-Time Digital Simulator (RTDS) lab with your control system hardware in the loop. This way, you know exactly how your SEL solution will behave when it’s installed.
