Simulation and Modelling of Electrical Insulation Weaknesses in Electrical Equipment
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.

Recent Topics in Electromagnetic Compatibility
Recent Topics in Electromagnetic Compatability discusses several topics in electromagnetic compatibility (EMC) and electromagnetic interference (EMI), including measurements, shielding, emission, interference, biomedical devices, and numerical modeling. Over five sections, chapters address the electromagnetic spectrum of corona discharge, life cycle assessment of flexible electromagnetic shields, EMC requirements for implantable medical devices, analysis and design of absorbers for EMC applications, artificial surfaces, and media for EMC and EMI shielding, and much more.
Distributed Generation Systems
Distributed Generation Systems: Design, Operation and Grid Integration closes the information gap between recent research on distributed generation and industrial plants, and provides solutions to their practical problems and limitations. It provides a clear picture of operation principles of distributed generation units, not only focusing on the power system perspective but targeting a specific need of the research community. This book is a useful reference for practitioners, featuring worked examples and figures on principal types of distributed generation with an emphasis on real-world examples, simulations, and illustrations. The book uses practical exercises relating to the concepts of operating and integrating DG units to distribution networks, and helps engineers accurately design systems and reduce maintenance costs. Provides examples and datasheets of principal systems and commercial data in MATLAB Presents guidance for accurate system designs and maintenance costs Identifies trouble shooting references for engineers Closes the information gap between recent research on distributed generation and industrial plants
Gas Discharge and Gas Insulation
This book presents a comprehensive overview of research on environmentally friendly insulating gases, in response to the urgent calls for developing alternatives to SF6 due to the increasing awareness of the threat it poses as a greenhouse gas. It covers gas dielectrics, SF6 and its mixtures, and potential alternative gases, providing fundamental information on gas discharge and gas insulation and especially focusing on the development of new environmentally friendly insulating gases over the last decade. The book begins by describing the insulating and arcing characteristics of SF6, followed by an introduction to the gas dielectrics performance of SF6 gas mixtures with buffer gases. The lat...
Power Transformer Condition Monitoring and Diagnosis
This must-read book on power transformer monitoring will incorporate current power transformer condition monitoring techniques from principles to practice. Each chapter will cover the fundamentals and theory of the topic, convey techniques to measure relevant parameters, and assess or interpret the results. The book will include factory acceptance tests, receiving end pre-commissioning tests, and commissioning tests. It will also include the limitations and challenges, and approaches to overcome these limitations.
Advances in Crowdsourcing
This book attempts to link some of the recent advances in crowdsourcing with advances in innovation and management. It contributes to the literature in several ways. First, it provides a global definition, insights and examples of this managerial perspective resulting in a theoretical framework. Second, it explores the relationship between crowdsourcing and technological innovation, the development of social networks and new behaviors of Internet users. Third, it explores different crowdsourcing applications in various sectors such as medicine, tourism, information and communication technology (ICT), and marketing. Fourth, it observes the ways in which crowdsourcing can improve product...
Votes, Drugs, and Violence
When widespread state-criminal collusion persists in transitions from autocracy to democracy, electoral competition becomes a catalyst of large-scale criminal violence.
Cultura y conciencia imperial en la España del siglo XIX
Mitjançant una exploració de diverses representacions culturals que es van dur a terme en la segona meitat del segle XIX, aquest volum mostra que en l'imaginari de l'Espanya metropolitana de l'època existia una identitat imperial que ha desaparegut quasi per complet de la historiografia contemporània. L'autora analitza les petjades de l'imperi que es troben en l'Exposició de les Illes Filipines a Madrid (1887) i la commemoració del IV Centenari del Descobriment d'Amèrica (1892), entre altres representacions del repertori simbòlic de l'imaginari nacional, i explora una sèrie de textos, objectes i pràctiques culturals que posen de manifest aquella consciència imperial que, fins a ben entrat el segle XX, estava imbricada en la identitat de la nació malgrat haver patit l'imperi dues importants descolonitzacions en 1824 i en 1898.
