Transmission-line reference book. 345 kV and above. Second edition
- ed.
This book is intended as a source of technology and data for the electrical design of EHV and UHV transmission lines up to 1500 kV. Much of the information was developed at Project UHV over the past twenty years. Four major design areas are treated: insulation design, corona performance, electric and magnetic fields, and circuit performance including conductor characteristics. In each area, a common set of base-case circuit designs is analyzed to help the design engineer understand and become sensitive to the items affecting design. Means to measure each discipline are fully explored. Insulation design for switching surge, lightning, and contamination is treated in depth. Stress versus strength arguments, together with strength data for all practical design situations, are featured for switching-surge design. A step-by-step analysis procedure for lightning insulation suitable for hand-held calculator use is an innovation in this book. For contamination, specific recommendations are made for insulator configurations from 345 to 1100 kV. The topics for corona performance are radio noise, audible noise, and corona loss. Design charts and equations as well as their underlying technology are developed in each of these areas for both single and double circuits. Special consideration to the concepts of generation, transmission, and detection is given for each parameter. Electric fields at ground level are treated in detail to support the goals of obtaining maximum field values and understanding the effects of electric fields on objects in the ROW. Mitigation means, calculation techniques, and effects of magnetic fields are also included. For convenience, tables of conductor and bundle phase characteristics, along with electric and magnetic transmission line parameters are presented for EHV and UHV base cases.
