High voltage engineering : fundamentals / E. Kuffel, W.S. Zaengl, J. Kuffel.

Includes bibliographical references and index.xiii, 239 p. :Power transfer for large systems depends on high system voltages. The basics of high voltage laboratory techniques and phenomena, together with the principles governing the design of high voltage insulation, are covered in this book for students, utility engineers, designers and operators of high voltage equipment. In this new edition the text has been entirely revised to reflect current practice. Major changes include coverage of the latest instrumentation, the use of electronegative gases such as sulfur hexafluoride, modern diagnostic techniques, and high voltage testing procedures with statistical approaches. A classic text on high voltage engineering Entirely revised to bring you uptodate with current practice Benefit from expanded sections on testing and diagnostic technique

High voltage engineering: fundamentals

Provides a comprehensive treatment of high voltage engineering fundamentals at the introductory and intermediate levels. It covers: techniques used for generation and measurement of high direct, alternating and surge voltages for general application in industrial testing and selected special examples found in basic research; analytical and numerical calculation of electrostatic fields in simple practical insulation system; basic ionisation and decay processes in gases and breakdown mechanisms of gaseous, liquid and solid dielectrics; partial discharges and modern discharge detectors; and ove

Elektro-Autos: Nein Danke Eine kritische Dokumentation

Elektrisch betriebene Automobile erfreuen sich in den letzten Jahren eines zunehmenden Interesses. Oekologische Versprechungen sollten jedoch nicht davon abhalten, dieses Transportmittels einmal kritisch zu hinterleuchten. Im Rahmen der vorliegenden Broschuere wird einleitend auf politische und wirtschaftliche Interessen bei der Durchsetzung von Elektromobilen eingegangen. Im weiteren wird aufgezeigt, warum das Elektroauto seine Versprechungen nicht einhalten kann. In diesem Zusammenhang wird auf folgende technische Einzelheiten eingegangen: Hybridantrieb, Wasserstoff, Brennstoffzelle, Batterie-Probleme, Heizung, Licht, Energie zur Herstellung von Elektroautos, zusaetzlicher Verkehr, CO_2-Problematik. (BWI)Electric-powered vehicles enjoy in the last years increasing attention. But ecological promises should not prevent from investigating this means of transport critically. In the introduction of this booklet political and economic interests pursued with the introduction of electric-powered vehicles are reported on. Then it is shown why electric-powered vehicles can not keep their promises. In this connection the following technical details are gone into: hybrid drive, hydrogen, fuel cells, battery problems, heating, lighting, energy for the production of electric-powered vehicles, additional traffic, CO_2 problem.

Development and application of new condition assessment methods for power transformers

Recent advances in the application of nontraditional methods and procedures for offline diagnosis and online monitoring of new and service-aged power transformers are discussed. Advanced offline methods are based on the main operational stresses (electrical, mechanical, thermal) and on typical failure modes: measurement of polarisation and depolarisation currents, electrical detection of partial discharges and measurement of the transfer function. A pilot installation of an online monitoring system on a strategically important transformer is described. The measured data of the built-in sensors (e.g. load, temperatures, gas and moisture in oil, overvoltages) are analyzed using a model-based software approach with an adaptive threshold to define faulty condition
