Extra High Voltage A. C. Transmission Engineering Description
Modern power transmission is utilizing voltages between 345 kV and 1150 kV, A.C. Distances of transmission and bulk powers handled have increased to such an extent that extra high voltages and ultra high voltages (EHV and UHV) are necessary. The problems encountered with such high voltage transmission lines exposed to nature are electrostatic fields near the lines, audible noise, radio interference, corona losses, carrier and TV interference, high voltage gradients, heavy bundled conductors, control of voltages at power frequency using shunt reactors of the switched type which inject harmonics into the system, switched capacitors, overvoltages caused by lightning and switching operations, long air gaps with weak insulating properties for switching surges, ground-return effects, and many more. The important topic of EHV cable transmission up to 1200 kV is gaining ground with oil-filled, PPLP, XLPE, and SF6 insulation. The book covers all topics that are considered essential for understanding the operation and design of EHV ac overhead lines and Underground cables. Theoretical analyses of all problems combined with practical application are presented in detail. EHV laboratory equipment and testing are fully covered together with application of digital recorders, fibre optics, etc. for impulse measurements. Every chapter contains many worked examples in order to illustrate and reinforce the theory. All examples are taken from practical situations as far as possible. About the Author(s): Rakosh Das Begamudre has been actively engaged in teaching, research, development and consulting in electrical machinery, control of machines and extra high voltage power transmission for nearly five decades at universities in India, United States and Canada. He holds the B.Sc. (Engineering) degree from the Banaras Hindu University (B.H.U.), the A.I.I.Sc. (Masters) degree from the Indian Institute of Science (Bangalore) and the Ph.D. degree from the Lehigh University in Bethlehem, Pennsylvania (U.S.A.). His training in large rotating machinery and transformer engineering was at the factories of Messrs HITACHI Ltd., in Japan. He was manager of Walden North Enterprises in Lillooet, Canada, working on motor control and energy problems. The author has worked with eminent professors in these fields such as Principal M. Sengupta at the B.H.U., Professor K. Aston at Roorkee University, Professors L.V. Bewley and A.R. Miller at Lehigh. He has held faculty positions at the universities of Mysore, Roorkee, Banaras, Lehigh, the Royal Military College of Canada and finally was Visiting Professor at l.l.T. Kanpur.
