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 E.H.V. Cable Transmission Upto 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 E.H.V. 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.

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.

This book covers all topics that are considered essential for understanding the operation and design of EHV AC lines. Theoretical analysis of all problems combined with practical application are presented.

Protection Technologies of Ultra-High-Voltage AC Transmission Systems considers the latest research on UHV, UHV transmission line electromagnetic field, transmission line parameters, and tower structures, with a focus on protective relaying of UHV transmission systems. This book gives insights into protective relaying of UHV AC transmission systems and sheds light on the conundrum of protective relaying for the EHV systems. In addition, it elaborates on both traditional relaying and the application of new type current differential protection, distance protection and automatic reclosing, as well as protective schemes for transformers and reactors in UHV transmission systems. This resource will serve as an important reference for technical personnel in network design and operation, as well as students and engineers in related engineering areas. Compares new advances and trends in Ultra-High-Voltage (UHV) transmission system from a global aspect Describes UHV protection technologies Evaluates conventional protection and novel protection principles in applied and verified global systems
