Foreword
It gives me pleasure to write the foreword to the book 'Extra High Voltage A.C. Transmission
Engineering' authored by Rakosh Das Begamudre, Visiting Professor in Electrical Engineering
at the Indian Institute of Technology, Kanpur. The field of e.h.v. is a very growing and dynamic
one on which depends to a large measure the industrial growth of a developing country like
ours. A course in this subject is offered for advanced under-graduate and postgraduate students,
and the Institute also organized a short-term course for teachers in other learned institutions
and practising engineers in India under the Quality Improvement Programme.
With a background of nearly 35 years in this area in India, Japan, U.S.A. and Canada in
teaching, design, research, and development, I consider Dr. Begamudre one of the ablest persons
to undertake the task of writing a book, placing his wide experience at the disposal of younger
engineers. He has worked at notable institutions such as the National Research Council of
Canada and the Central Power Research Institute, Bangalore, and several other places. His
publications in the field of e.h.v. transmission are numerous and varied in extent. The I.I.T.
Kanpur offered him Visiting Professorship and I am delighted to introduce the book by him to
learned readers in this important field. It is not only a worthy addition to the technical literature
in this topic but also to the list of text books published in India.

Preface to the Third Edition
It is nearly a decade since the publication of the Second Edition of this text-reference book
authored by me and needs a revision. No significant developments have taken place in the
basic theory and principles of e.h.v. transmission engineering, except for increase in
transmission-voltage levels, cables, magnitudes of power-handling capabilities, as well as of
course the cost of equipment and lines.
But two problems that need mentioning are: (1) harmonics injected into the system by
modern extensive use and developments in Static VAR systems which have an effect on control
and communication systems; and (2) effect on human health due to magnetic fields in the
vicinity of the e.h.v. transmission line corridor. The first one of these is a very advanced topic
and cannot be included in a first text on e.h.v. transmission engineering, as well as several
other topics of a research nature fit for graduate-level theses and dissertations. The second
topic is considered important enough from epidemiological point of view to necessitate
elaboration. Thus a new addition has been made to Chapter 7 under the title: Magnetic Field
Effects of E.H.V. Lines.
Since the date of publication of the first edition, the I.E.E.E. in New York has thought it
fit to introduce an additional transactions called I.E.E.E. Transactions on Power Delivery. The
author has expanded the list of references at the end of the text to include titles of significant
technical papers pertaining to transmission practice.
The author wishes to acknowledge the encouragement received from Sri. V.R. Damodaran,
Production Editor, New Age International (P) Ltd., for revising this text-reference book and
preparation of the Third Edition.
