New Trends In High Voltage Engineering

For public access to electric energy, exploitation of high-voltage networks is inevitable. Meanwhile, high-voltage engineering plays a basic role in designing and operating network insulation. On the other hand, modern high-voltage engineering trends are developing environmentally friendly and recyclable insulators. Recently, nano-doping of environmentally friendly polypropylene/inorganic nano-composites has shown improvement to its characteristics and increased the use of HVDC insulation. In this book, research is carried out on nano-doping effects on the performance and future development of polypropylene nano-composites. Also, the characteristics of CF3I gas and its combination with nitrogen by experimental results are investigated. Installation of capacitors may result in voltage increment at the point where the capacitors are connected to the network. This issue is important when a harmonic resonance has occurred. The harmonic resonances may lead to voltage stress on the power network insulation. The book also discusses the effect of harmonic resonance on the insulation.

High voltage, Electrical engineering, Electronic engineering, Electrical testing, Building and Construction

Demand for electricity is rising at faster speed than ever before with rapidly evolving technologies. To encounter the growing demand, the generation capacity is to be improved as well as proficiently transported over large distances with minimum losses. It is observed that an ultra-high-voltage transmission line would be more suitable for transfer of bulk power efficiently. One of the key concerns in transmission of electricity is power loss in transmission lines, dissipated as heat due to the resistance of the conductors. The smaller the surface area of the conductors, the smaller the loss to heat dissipation. High voltages require less surface area, resulting in reduced line loss. With high-voltage lines, the voltage can be stepped up at the generating station, transmitted through the transmission grid to a load center, and there stepped down to the lower voltages required by distribution lines. Thus it is vital that the electrical engineers need be equipped with the latest research and development issues in high voltage technology. This emphasizes the need for engineering/technical institutions and practicing high voltage engineers to know modern techniques for increasing power generation as well efficiently transmitting it. Higher and higher voltage for power transmission has been a fascinating subject of research after the advantages of EHV transmission was realized nearly a century back. High Voltage Engineering integrates state of the art reviews and real cases in high-voltage techniques, to provide an understanding of high-voltage phenomena, and to present the basics of high voltage insulation design together with the analytical and modern numerical tools available to high-voltage equipment designers. An attempt has been made to study the major research areas in High Voltage discipline. This book also presents the coverage of innovative developments and future trends in high-voltage technology.This book will be of conversant to advanced graduate students and practicing engineers engaged in the design and operation of high-voltage equipment.

The new edition of this book incorporates the recent remarkable changes in electric power generation, transmission and distribution. The consequences of the latest development to High Voltage (HV) test and measuring techniques result in new chapters on Partial Discharge measurements, Measurements of Dielectric Properties, and some new thoughts on the Shannon Theorem and Impuls current measurements. This standard reference of the international high-voltage community combines high voltage engineering with HV testing techniques and HV measuring methods. Based on long-term experience gained by the authors the book reflects the state of the art as well as the future trends in testing and diagnostics of HV equipment. It ensures a reliable generation, transmission and distribution of electrical energy. The book is intended not only for experts but also for students in electrical engineering and high-voltage engineering.
