Application of Tap changers to Transformers

This book focuses on the role and application of tap changers to power transformers and the power transmission industry in general. Starting with an elementary introduction to the fundamentals of tap changers, the book discusses the evolution of resistance tap changers and their current applications. It also includes the most recent technologies in the field like the vacuum and reactor tap changers, and discusses the driving mechanisms, operations and maintenance. This book can be a very useful reference for power systems professionals, engineering consultants, transformer manufacturers, and R&D organizations in the specification, installation, operation and maintenance of tap changers. 

Dr. T. V. Sridhar obtained his PhD from Imperial College London in 1966, after finishing his Bachelors in Engineering from Bombay University, India in 1960. He had a vast experience of more than 40 years in the industry having worked in different capacities from Deputy Chief Design Engineer (Transformers) at Hackbridge Hewittic & Easun Limited to Director (R&D) at On Load Gears (OLG), Chennai. During his time at OLG, he had established a product line of external and internal tap changers, resistance and reactor type, dry and oil type with vacuum technology. Dr. Sridhar also briefly worked as a Lecturer at the University College, Nairobi, Kenya between 1966 and 1968. During his extensive career, he had published several research articles in international peer-reviewed journals.
