Extra High Voltage AC Transmission Engineering

Presented in a lucid style with easy-to-understand methodology; Review Questions, Problems with Answers are given; The material has been tried out for advanced undergraduate and postgraduate courses at reputed institutions.

The book covers all topics that are considered essential for understanding the operation and design of EHV, AC overhead lines and underground cables. Theoretical analysis 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.
