Distribution automation can improve the speed, cost, and accuracy of several key distribution system processes, including fault detection, feeder switching, and outage management; voltage monitoring and control; reactive power management; preventative equipment maintenance. Distribution automation can improve the speed, cost, and accuracy of several key distribution system processes, including fault detection, feeder switching, and outage management; voltage monitoring and control; reactive power management; preventative equipment maintenance. OVERLAY VS. 50 Distribution automation (DA) is a family of technologies, including sensors, processors, information and communication networks, and switches, through which a utility can collect, automate, analyze, and optimize data to improve the operational efficiency of its distribution power system. Distribution systems have traditionally not involved much automation. Distribution equipment, once installed on feeders, was expected. The handbook describes various power distribution system constructions and elements there-of, technical considerations, distribution automation infrastructure and functionality, communication aspects, special automation applications and life cycle aspects.
