The constant variations in line and source topologies found in a typical automated distribution feeder can create design challenges for protection engineers, especially those using traditional overcurrent protection methods. A novel approach using differential protection recently debuted on an A&N Electric Cooperative feeder in Virginia, demonstrating the ability to reduce the number of required settings groups without compromising feeder flexibility or the speed, accuracy, and selectivity of protection.
