With distributed generation interconnection power flow becoming bidirectional, culminating in network problems, smart grids aid in electricity generation, transmission, substations, distribution and consumption to achieve a system that is clean, safe (protected), secure, reliable, efficient, and sustainable. This book illustrates fault analysis, fuses, circuit breakers, instrument transformers, relay technology, transmission lines protection setting using DIGsILENT Power Factory. Intended audience is senior undergraduate and graduate students, and researchers in power systems, transmission and distribution, protection system broadly under electrical engineering.

Professor Ramesh Bansal, who has more than 25 years’ experience in teaching, research and industry, is currently based in College of Engineering, University of Sharjah, UAE. Prior to this, he was a a professor and Group Head (Power) in the Department of Electrical, Electronic and Computer Engineering at University of Pretoria, and niversity of Queensland in Australia, the University of the South Pacific in Fiji, the Birla Institute of Technology and Science in Pilani, India, and the Civil Construction Wing of All-India Radio. He has worked with Powerlink, an Australian government-owned corporation responsible for Queensland’s high-voltage electricity transmission network.

Prof. Bansal has significant industrial experience of collaborating with power utilities around word which includes NTPC (A 40 GW Indian Power Generation Company), Powerlink, & ESKOM. Professor Bansal has published more than 300 journal articles, presented papers at conferences, and has contributed to books and chapters in books. He has supervised 18 PhD students and currently supervising several PhDs students. His diversified research interests are in the areas of renewable energy and conventional power systems which include wind, photovoltaics (PV), hybrid power systems, distributed generation, grid integration of renewable energy, power systems analysis and Power System Protection. Professor Bansal is an Editor/Associate Editor of the highly regarded journals, IET-Renewable Power Generation (regional editor for Africa) Electric Power Components and Systems, and Technology and Economics of Smart Grids and Sustainable Energy. He is a fellow and a chartered engineer of the Institution of Engineering and Technology, UK, a fellow of Engineers Australia, a fellow of the Institution of Engineers (India) and a senior member of the Institute of Electrical and Electronics Engineers (IEEE).
