System-Wide Automation Solution Prolongs Life of Existing Relays

“We knew we were going to have trouble developing that [technical strategy] in-house. SEL had the expertise that we didn’t have.”
Don NannySenior Manager of System Analysis and Control, Chattanooga EPB


With the new motor-operated switches and automation of their entire subtransmission system (including areas protected by electromechanical relays), EPB can restore power faster than ever before after an outage. If their service territory experiences a major event, EPB can now depend on automatic fault location, isolation, and service restoration to bring the majority of customers back online. EPB has visibility into their entire subtransmission system and can determine which areas need to be repaired before they send technicians into the field.
