Dielectric Materials for Electrical Engineering
Author: Juan Martinez-VegaPublisher: John Wiley & Sons
ISBN: 1118619781
Category : Technology & Engineering
Languages : en
Pages : 443
Book Description
The object of this book is to provide a comprehensive reference source for the numerous scientific communities (engineers, researchers, students, etc.) in various disciplines which require detailed information in the field of dielectric materials. Part 1 focuses on physical properties, electrical ageing, and modeling - including topics such as the physics of charged dielectric materials, conduction mechanisms, dielectric relaxation, space charge, electric ageing and end of life (EOL) models, and dielectric experimental characterization. Part 2 examines applications of specific relevance to dielectric materials: insulating oils for transformers, electro-rheological fluids, electrolytic capacitors, ionic membranes, photovoltaic conversion, dielectric thermal control coatings for geostationary satellites, plastics recycling and piezoelectric polymers.
Simulation and Modelling of Electrical Insulation Weaknesses in Electrical Equipment
Author: Ricardo Albarracín SánchezPublisher: BoD – Books on Demand
ISBN: 1789237688
Category : Technology & Engineering
Languages : en
Pages : 216
Book Description
Around 80% of electrical consumption in an industrialised society is used by machinery and electrical drives. Therefore, it is key to have reliable grids that feed these electrical assets. Consequently, it is necessary to carry out pre-commissioning tests of their insulation systems and, in some cases, to implement an online condition monitoring and trending analysis of key variables, such as partial discharges and temperature, among others. Because the tests carried out for analysing the dielectric behaviour of insulation systems are commonly standardised, it is of interest to have tools that simulate the real behaviour of those and their weaknesses to prevent electrical breakdowns. The aim of this book is to provide the reader with models for electrical insulation systems diagnosis.
Advances in Life Cycle Engineering for Sustainable Manufacturing Businesses
Author: Shozo TakataPublisher: Springer Science & Business Media
ISBN: 1846289351
Category : Technology & Engineering
Languages : en
Pages : 474
Book Description
Life cycle engineering explores technologies for shifting industry from mass production and consumption paradigms to closed-loop manufacturing paradigms, in which required functions are provided with the minimum amount of production. This subject is discussed from various aspects: life cycle design, design for environment, reduce-reuse-recycle, life cycle assessment, and sustainable business models. This book collects papers from the 14th International CIRP Life Cycle Engineering Conference, the longest-running annual meeting in the field.
Converter Applications and their Influence on Large Electrical Machines
Author: Oliver DrubelPublisher: Springer Science & Business Media
ISBN: 3642362826
Category : Technology & Engineering
Languages : en
Pages : 195
Book Description
Converter driven applications are applied in more and more processes. Almost any installed wind-farm, ship drives, steel mills, several boiler feed water pumps, extruder and many other applications operate much more efficient and economic in case of variable speed solutions. The boundary conditions for a motor or generator will change, if it is supplied by a converter. An electrical machine, which is operated by a converter, can no longer be regarded as an independent component, but is embedded in a system consisting of converter and machine. This book gives an overview of existing converter designs for large electrical machines. Methods for the appropriate calculation of machine phenomena, which are implied by converters are derived in the power range above 500kVA. It is shown how due to the converter inherent higher voltage harmonics and pulse frequencies special phenomena are caused inside the machine which can be the reason for malfunction. It is demonstrated that additional losses create additional temperature increases or voltage peaks. The book describes how torque ripple can occur, which endanger the mechanical shaft system and last but not least shaft voltages are induced, which are sometimes sufficient in amplitude to damage bearings or to disturb sensors of the protection arrangements.
Discharge in Long Air Gaps
Author: Abderrahmane BeroualPublisher: IOP Publishing Limited
ISBN: 9780750312370
Category : Science
Languages : en
Pages : 0
Book Description
'Discharge in Long Air Gaps' presents self-consistent predictive dynamic models of positive and negative discharges in long air gaps. Equivalent models are also derived to predict lightning parameters based on the similarities between long air gap discharges and lightning flashes. Comparisons between computed and experimental results for various test configurations are presented and discussed.

Electrical Insulation for Rotating Machines
Author: Greg C. StonePublisher: John Wiley & Sons
ISBN: 1118892291
Category : Technology & Engineering
Languages : en
Pages : 685
Book Description
A fully expanded new edition documenting the significant improvements that have been made to the tests and monitors of electrical insulation systems Electrical Insulation for Rotating Machines: Design, Evaluation, Aging, Testing, and Repair, Second Edition covers all aspects in the design, deterioration, testing, and repair of the electrical insulation used in motors and generators of all ratings greater than fractional horsepower size. It discusses both rotor and stator windings; gives a historical overview of machine insulation design; and describes the materials and manufacturing methods of the rotor and stator winding insulation systems in current use (while covering systems made over fifty years ago). It covers how to select the insulation systems for use in new machines, and explains over thirty different rotor and stator winding failure processes, including the methods to repair, or least slow down, each process. Finally, it reviews the theoretical basis, practical application, and interpretation of forty different tests and monitors that are used to assess winding insulation condition, thereby helping machine users avoid unnecessary machine failures and reduce maintenance costs. Electrical Insulation for Rotating Machines: Documents the large array of machine electrical failure mechanisms, repair methods, and test techniques that are currently available Educates owners of machines as well as repair shops on the different failure processes and shows them how to fix or otherwise ameliorate them Offers chapters on testing, monitoring, and maintenance strategies that assist in educating machine users and repair shops on the tests needed for specific situations and how to minimize motor and generator maintenance costs Captures the state of both the present and past “art” in rotating machine insulation system design and manufacture, which helps designers learn from the knowledge acquired by previous generations An ideal read for researchers, developers, and manufacturers of electrical insulating materials for machines, Electrical Insulation for Rotating Machines will also benefit designers of motors and generators who must select and apply electrical insulation in machines.
