Innovative Power System Controls and Protection Systems

SEL substation solutions include Job Done® control enclosures that are delivered fully tested and ready for service. Wind, solarthermal, solar-PV, geothermal, and waste-to-energy systems commonly employ SEL intertie, synchrophasor, and metering solutions so that energy flows are protected, properly metered, and delivered to the grid without interruption. Our faulted circuit indicators (FCIs) help system operators troubleshoot cabling problems quickly and minimize downtime.
