The technology improves electric service reliability through intelligent automation that isolates faults within a smaller section of the distribution system, significantly reducing the number of customers experiencing a power outage. According to Efacec ACS, “Many outages that occur due to a fault can often be quickly restored by automatically re-routing power from another portion of the system.”
Primary benefits of FDIR include shorter outage durations; fewer sustained outages; improved network performance; greater operational efficiency; and improved service delivery.
Bhaji Dhillon, Cobb EMC manager of power system technologies and planning, explains: “The ability to automatically isolate and restore faults on distribution feeders is an advanced technology that we’re excited to be able to provide for Cobb EMC members. Over the years we have aggressively deployed automation on our system to improve the reliability of service to our members, with over 650 SCADA-controlled switches installed. Deployment of FDIR on our distribution management system (DMS) from Efacec ACS is the next step in leveraging this installed infrastructure.”
Before activating FDIR, Cobb EMC evaluated the technology and tuned the network model while operating the system in a manual mode.
Efacec ACS’ chief executive officer Jose Barbosa adds: “Cobb EMC has been a valuable partner and customer from the inception of our company over 37 years ago. We are pleased to be able to continue working with them to deploy advanced DMS applications like FDIR to help them provide excellent service and reliability to their members.”
