This book covers the diagnosis and assessment of the various faults which can occur in a three phase induction motor, namely rotor broken-bar faults, rotor-mass unbalance faults, stator winding faults, single phasing faults and crawling.

Following a brief introduction, the second chapter describes the construction and operation of an induction motor, then reviews the range of known motor faults, some existing techniques for fault analysis, and some useful signal processing techniques. It includes an extensive literature survey to establish the research trends in induction motor...

When installed and operated properly, general purpose steam turbines are reliable and tend to be forgotten, i.e., out of sound and out of mind. But, they can be sleeping giants that can result in major headaches if ignored. Three real steam turbine undesirable consequences that immediately come to mind are:

• Injury and secondary damage due to an overspeed failure. An overspeed failure on a big steam or gas turbine is one of the most frightening of industrial accidents.
• The high cost of an extensive overhaul due to an undetected component failure. A major steam turbine...

Ein wachruttelndes Fragebuch uber die radioaktive Strahlenbelastung. Die deutschen Atomkraftwerke sollen abgeschaltet werden. Um den Strom aus regenerativen Quellen transportieren zu konnen, wird das Stromnetz ausgebaut. Neben den schon bekannten Konsequenzen aus den geplanten Hochspannungstrassen wird die Frage beleuchtet, ob weitere Konsequenzen bisher unberucksichtigt blieben. Werden die geplanten Gleichstromtrassen zu einer radioaktiven Belastung fuhren? Fur Laien und von einem Nicht-Fachmann geschrieben, wird das notwendige Basiswissen leichtverdaulich vermittelt, der aktuelle Stand...

The book addresses the problem of passivation at the surface of crystalline silicon solar cells. More specifically, it reports on a high-throughput, industrially compatible deposition method for Al2O3, enabling its application to commercial solar cells. One of the main focus is on the analysis of the physics of Al2O3 as a passivating dielectric for silicon surfaces. This is accomplished through a comprehensive study, which moves from the particular, the case of aluminium oxide on silicon, to the general, the physics of surface recombination, and is able to connect theory with...

The technical and economic analysis presented here extend the available knowledge in the field of investment optimization in energy engineering, while also enabling investors to make decisions involving its application. Individual chapters explore the potential impacts of different factors like...

Dieses Praxisbuch bietet eine fundierte Hilfe bei der Berechnung und Konstruktion der hydrodynamischen Komponenten von radialen Kreiselpumpen.

Fur das Grundverstandnis der sehr komplexen Zusammenhange in der Pumpenhydrodynamik werden zunachst die grundlegenden physikalischen Gesetzmassigkeiten hergeleitet und verstandlich erklart. Im Weiteren werden neue Berechnungsverfahren vermittelt, wie z.B. Methoden zur Berechnung der Minderleistung, der Laufradbeschaufelung und des Laufradeintrittsquerschnitts, der verschiedenen Leitvorrichtungen, der Scheibenreibungsverluste und des...

Dieses Buch behandelt ein hochaktuelles Thema der Energiewende: Mit der Liberalisierung der Energieversorgung und der gesetzlichen Forderung erneuerbarer und ressourcenschonender Erzeugungstechniken setzte eine grundlegende Umstrukturierung der elektrischen Energieversorgung ein. Diese findet vorwiegend in Verteilnetzen statt.

Einleitend erlautert das Buch dazu die gesetzlichen Grundlagen. Im Anschluss werden die Technologien dezentraler Elektroenergieerzeugung vorgestellt. Schwerpunkte bilden deren elektrische Eigenschaften und Erzeugungscharakteristiken. Der folgende Buchteil...

Food Processing Technology: Principles and Practice, Fourth Edition, has been updated and extended to include the many developments that have taken place since the third edition was published. The new edition includes an overview of the component subjects in food science and technology, processing stages, important aspects of food industry management not otherwise considered (e.g. financial management, marketing, food laws and food industry regulation), value chains, the global food industry, and over-arching considerations (e.g. environmental issues and sustainability).

In...
