Company Overview

SEL offers complete power system awareness, protection, and automation solutions, from advanced IEC 61850 GOOSE power management to secure operational technology (OT) high-speed networks. We provide easy-to-use protective relays (including arc-flash detection), controllers, computers, and meters. To help improve asset utilization and reduce the costs of downtime, SEL solutions also offer microgrid management; remediation schemes for plant disruptions; quick identification of problem sources; and advanced warning of maintenance conditions. Power systems are the heart of your plant and behave differently than traditional factory automation, requiring subcycle speeds and coordination of dynamic loads. Integrating power system information with your PlantPAx® HMI is a simple process, and we can show you how. SEL provides free local engineering support, and our products come with a standard ten-year warranty.
