The basic theory, principle of operation and characteristics of transformers, three-phase induction motors, single-phase induction motors, synchronous machines and dc machines are dealt with in Appendices to provide the background for the design of these machines. The initial chapters of the book are devoted to basic parameters of design of electrical apparatus, characteristics of magnetic, electric and insulating materials, construction of electrical machines, and basic design requirements of magnetic and electrical circuits of machines. Detailed procedures for designing transformers, three-phase induction motors, single-phase induction motors, synchronous machines and dc machines are explained in a simple and logical way. Several sample designs have been wroked out in detail. Methods of carrying out various tests and maintaining test records are discussed in detail. The use of computers in designing electrical machines has been illustrated. An exclusive chapter on special machines explains the basic theory and applications of stepper motors, rotating phase converters, pole amplitude modulated (PAM) motors, reluctance motors and energy efficient motors. This book is intended for degree and diploma students of electrical engineering and professional examinations of the Institution of Engineers (India). It will be useful for electrical engineers in industry engaged in design, manufacture and testing of electrical machines.

Prevention is better than cure and proper cure needed if a problem arises. Maintenance is the key for both preventions and cures. This book devoted to the electrical substation design and analysis and subjected to represent the maintenance of all types of electrical equipments. In this book the maintenance schedule for the associated equipments to the substation installation, commissioning and testing are highlighted with brief explanation. This book covers all vital equipments serving the substation for power demands by both domestic and industrial applications. In this book, making or preparing maintenance schedule of dc machines, induction machines, synchronous machines, transformer, transmission line, distribution lines, underground cables, circuit breakers, switchgear, protective relays, sf-6 circuit breakers, batteries in substation are presented with considering the electricity rules and regulations provide by the government. This book will be very helpful for the students of under graduated and post graduate studies in technical and skill development institutions. Various technical books, technical firms, research papers, technical manuals, notes of various educational firms and books associated to the title considered to enhance the quality of the literature for better understandings. Electrical equipment must be serviced and tested on a regular basis in order to get the most out of it, maintain its dependability, and reduce maintenance costs. Electrical equipment maintenance and overall safety are receiving more and more attention. Many communities are enacting regulations and codes requiring periodic inspection and testing of large electrical facilities within their jurisdictions; the federal government has passed laws requiring substation maintenance; and insurance companies are basing premiums on the quality of a facility's maintenance program and equipment condition.

The modern microprocessor based electronic equipment most vulnerable to Intentional Destructive Electromagnetic Interferences (IDEI) includes High-Altitude Electromagnetic Pulse (HEMP) in all substation equipment. However, power equipment and especially transformers are also subject to the influence of HEMP. The book discusses problems and solutions for both kinds of substation equipment. Separated into eight chapters, the book covers: Technological progress and its consequences; Intentional Destructive Electromagnetic Interferences (IDEI); Methods and means of Digital Protective Relay (DPR) protection from electromagnetic pulse; Passive methods and means of DPR protection from electromagnetic pulse; Active methods and means of DPR protection from electromagnetic pulse; Tests of DPR resistance to IDEI impacts; Organizational and technical measures to protect DPR from HEMP; and Protection of power equipment and transformers from HEMP. Key features: Practical approach focusing on technical solutions for difficult problems. Full data on electromagnetic threats and methods of their prevention are concentrated. Addresses a gap in knowledge in the power system industry. This book emphasizes practical recommendations on protection of power substations' electric equipment from IDEI that intended for not only staff operating electric equipment, but also for manufacturers of this equipment, specialists of designing companies, managers of electric energy industry as well as for teachers and postgraduate students.

On cover: Reclamation, Managing Water in the West. Describes how transformers work, how they are maintained, and how to test and evaluate their condition.

Combining select chapters from Grigsby's standard-setting The Electric Power Engineering Handbook with several chapters not found in the original work, Electric Power Substations Engineering became widely popular for its comprehensive, tutorial-style treatment of the theory, design, analysis, operation, and protection of power substations. For its
