Distribution Automation (DA) includes different technologies and protocols such as processors, sensors, switches and communication that monitor and control electric distribution system without human involvement. It increases distribution system’s efficiency by energy and system loss saving, increases distribution system’s reliability by decreasing frequency and duration of power outages and also increases flexibility by enabling higher penetration of distributed energy resources. Distribution automation increases utilization and efficiency of distribution system and also enables cost-effective penetration of DER (Distributed energy resources) as an option to build central generating stations. Automation of distribution system ensures reduction in operational and maintenance cost, which is expected to drive the growth of distribution automation system market over the forecast period. In addition, it reduces outage time by detecting, isolating and restoring the fault in advance, which is
