Add to basketHardback. Condition: New. An introduction to a cutting-edge, environmentally friendly insulation material The installation and maintenance of high-voltage cables is an infrastructure problem with potentially major environmental impacts. In recent years, polypropylene has emerged as an environmentally friendly material for insulating high-voltage cables, particularly HVDC power cables and HVAC power cables. Polypropylene Cable Insulation begins with an introduction to high-voltage cables and the development of polypropylene insulation before describing the dielectric properties and applications of this insulation in both HVDC and HVAC contexts. The result is a thorough, accessible guide to an essential part of any environmentally friendly power grid. Readers will also find: Detailed explorations of the relationship between space charge behaviors and trap characteristics Discussion of topics including polarization and dielectric relaxation, electrical treeing degradation, partial discharge, and moreGraphs and tables illustrating experimental results Polypropylene Cable Insulation is ideal for electrical power engineers, power transmission system operators, and any engineers or researchers working in power transmission and/or distribution cables.

Condition: Hervorragend. Zustand: Hervorragend | Seiten: 516 | Sprache: Englisch | Produktart: Bücher | This book offers an insight into the insulation failures in GIS/GIL and provides practical guidance for improving the insulation reliability of epoxy-based spacers. High voltage gas-insulated apparatuses, including gas-insulated switchgears (GIS) and transmission lines (GIL), playing an important role in the global power transmission system. Epoxy-based spacers are key components in GIS/GIL, playing the role of electrical insulation and mechanical support. However, insulation failures frequently occur around the epoxy-based spacers, threatening the safe operation of the electric power system. Three topics make up this book, with seven to nine chapters in each topic. In the first topic, the surface charging and discharging behaviors of epoxy-based spacers are discussed to deepen the readersż understanding on the insulation problems in GIS/GIL. And the insulation breakdown of epoxy-based spacers is found to be closely related to the electric field distortion under complex operating conditions. In the second topic, original researches on the surface functionally graded materials (SFGM) are presented for relaxing the electric field distortion around the epoxy-based spacers in both AC and DC GIS/GIL, and a series of optimization methods and fabrication techniques for the SFGM spacers are introduced and discussed. In the last topic, the nonlinear conductivity materials (NCM), also known as self-adaptive materials or intelligent materials, are applied as coatings to adaptively regulate the electric field distributions along the surfaces of the epoxy-based spacers. Besides, the concept of the multi-dimensional functionally graded materials (MFGM) is proposed to uniform the electric field distributions in DC GIS/GIL under stationary and transient voltages, exhibiting great potential in the future application.

Hardcover. Condition: new. Hardcover. Polypropylene film is the most widely used dielectric material in HVDC capacitors. As the voltage level and transmission capacity of the power system increase, the dielectric properties of polypropylene film become more demanding. In recent years, researchers have studied the modification methods of polypropylene film to improve its breakdown field strength and energy storage density under operating conditions, and to reduce its dielectric loss. This book comprehensively reports the relevant research on polypropylene film for HVDC capacitors. The book details the application background, fundamental properties and related theories of polypropylene dielectrics. The relationship between the microstructure and the dielectric properties of polypropylene films is described, and the insulation failure mechanism of polypropylene is discussed. The modification methods of polypropylene energy storage media including ash washing, molecular chain structure regulation, aggregation structure regulation, nanoparticle doping, polyphenyl ring compound modification, cycloolefin copolymer blending and interfacial molecular regulation are reviewed. The effects of high temperature and strong magnetic field on the dielectric properties of polypropylene films are discussed and the high temperature and strong magnetic field resistant polypropylene dielectrics are presented.The book contains the dielectric constant, conductivity, breakdown field strength, energy storage density and other relevant graphs and data of modified polypropylene film under different operating conditions, which clearly explains the improvement effect of various modification methods on the dielectric properties of polypropylene film. This book provides a comprehensive reference for the research of polypropylene film for HVDC capacitors. It can help students, researchers and technicians in related industries to understand the insulation failure mechanism of polypropylene film and make readers understand the latest modification methods to improve the dielectric performance of PP films.
