High Voltage Engineering (EET 417/3)

Based on the latest of this successful series of IEE Vacation Schools, this fully revised and updated book aims to provide a sound appreciation of present day HV transmission equipment design and testing techniques. Within the book there is coverage of all the key components of HV power systems, together with HV transmission and distribution, commercial considerations and testing, measurement and accreditation.

Inspired by a new revival of worldwide interest in extra-high-voltage (EHV) and ultra-high-voltage (UHV) transmission, High Voltage Engineering merges the latest research with the extensive experience of the best in the field to deliver a comprehensive treatment of electrical insulation systems for the next generation of utility engineers and electric power professionals. The book offers extensive coverage of the physical basis of high-voltage engineering, from insulation stress and strength to lightning attachment and protection and beyond. Presenting information critical to the design, selection, testing, maintenance, and operation of a myriad of high-voltage power equipment, this must-have text: Discusses power system overvoltages, electric field calculation, and statistical analysis of ionization and breakdown phenomena essential for proper planning and interpretation of high-voltage tests Considers the breakdown of gases (SF6), liquids (insulating oil), solids, and composite materials, as well as the breakdown characteristics of long air gaps Describes insulation systems currently used in high-voltage engineering, including air insulation and insulators in overhead power transmission lines, gas-insulated substation (GIS) and cables, oil-paper insulation in power transformers, paper-oil insulation in high-voltage cables, and polymer insulation in cables Examines contemporary practices in insulation coordination in association with the International Electrotechnical Commission (IEC) definition and the latest standards Explores high-voltage testing and measuring techniques, from generation of test voltages to digital measuring methods With an emphasis on handling practical situations encountered in the operation of high-voltage power equipment, High Voltage Engineering provides readers with a detailed, real-world understanding of electrical insulation systems, including the various factors affecting--and the actual means of evaluating--insulation performance and their application in the establishment of technical specifications.

High Voltage Engineering has been written for the undergraduate students in Electrical Engineering of Indian and foreign universities as well as the practising engineers. It deals in mechanism of breakdown of insulating materials, generation and measurement of high A.C., D.C., impulse voltages and currents. High voltage testing of some of the electrical equipments e.g. insulators, cables, transformers as per standard specifications has been explained. Various methods of non destructive testing which yield information regarding life expectancy and the long term stability or otherwise of the insulating materials have been discussed. The book takes a view of various types of transients in power system and suggests classical and more modern statistical methods of co-ordinating the insulation requirements of the system.
