Residential, Commercial and Industrial Electrical Systems is a comprehensive coverage on every aspect of design, installation, testing and commissioning of electrical systems for residential, commercial and industrial buildings. This book would serve as a ready reference for electrical engineers as well as bridge the gap between theory and practice, for students and academicians, alike. Vol.3: Protection, Testing and Commissioning discusses various aspects of protection, testing and commissioning of electrical systems. This book elaborately presents advanced topics like harmonics and interference, various testing procedures and practices necessary to avoid premature failure of electrical equipment. Embellished with over 150 illustrations, graphs and tables, this volume covers:* Earthing* Lightning Protection of buildings, switchyard and lines* Overvoltage protection of equipment* Harmonics, electromagnetic interference and induction* Fault level calculations and protection relaying* Testing of equipment at factory level as well as on-site Salient Features Vol.3: Protection, Testing and Commissioning discusses various aspects of protection, testing and commissioning of electrical systems.
