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. This White Paper, “Smart Grid for Distribution Systems” addresses the benefits and challenges of implementing the many different Distribution Automation functions. Electric utility companies are under increasing pressure to improve reliability, minimize customer outages and optimize. One key solution to this challenge is the adoption of distribution automation (DA) systems, which offer benefits including improved system reliability, enhanced crew safety and reduced outage durations.
