As engineering processes are automated and manpower is reduced, condition monitoring of engineering plants has increased in importance. This is a first edition of this book, written by Taver & Penman was published in 1987. The economics of industry has now changed, as a result of the privatization and deregulation of the energy industry, placing far more emphasis on the importance of the reliable operation of a plant, throughout the whole life-cycle, regardless of first cost. The availability of advanced electronics and software in powerful instrumentation, computers and Digital Signal Processors (DSP) has simplified our ability to instrument and analyze machinery. As a result condition monitoring is now being applied to a wider range of systems, from fault-tolerant drives of a few hundred Watts in the aerospace industry, to machinery of a few hundred Megawatts in major capital plants.In this new book the original authors have been joined by Li Ran an expert in power electronics and control, and Sedding, an expert in the monitoring of electrical insulation systems. The first edition has been revised and expanded merging the authors' own experience with that of machine analysts to bring it up-to-date.

Provides coverage of Motor Current Signature Analysis (MCSA) for cage induction motors This book is primarily for industrial engineers. It has 13 chapters and contains a unique data base of 50 industrial case histories on the application of MCSA to diagnose broken rotor bars or unacceptable levels of airgap eccentricity in cage induction motors with ratings from 127 kW (170 H.P.) up to 10,160 kW (13,620 H.P.). There are also unsuccessful case histories, which is another unique feature of the book. The case studies also illustrate the effects of mechanical load dynamics downstream of the motor on the interpretation of current signatures. A number of cases are presented where abnormal operation of the driven load was diagnosed. Chapter 13 presents a critical appraisal of MCSA including successes, failures and lessons learned via industrial case histories. The case histories are presented in a step by step format, with predictions and outcomes supported by current spectra and photographic evidence to confirm a correct or incorrect diagnosis The case histories are presented in detail so readers fully understand the diagnosis The authors have 108 years of combined experience in the installation, maintenance, repair, design, manufacture, operation and condition monitoring of SCIMs There are 10 questions at the end of chapters 1 to 12 and answers can be obtained via the publisher Current Signature Analysis for Condition Monitoring of Cage Induction Motors serves as a reference for professional engineers, head electricians and technicians working with induction motors.

Prof. Thomson received a BSc (Hons) in Electrical Engineering in 1973 and an MSc in 1977 from the University of Strathclyde. He has published 72 papers on condition monitoring of induction motors in a variety of engineering journals such as IEEE Transactions (USA), IEE Proceedings (UK), and also at numerous International IEEE and IEE conferences. He is a senior member of the IEEE, a fellow of the IEE (IET) in the UK and a Chartered Professional Engineer registered in the UK. Ian Culbert was a Rotating Machines Specialist at Iris Power Qualitrol since April 2002 until his very untimely death on 8th September, 2015. At this company he provided consulting services to customers, assisted in product development, trained sales and field service staff and reviewed stator winding partial discharge reports. He has co-authored two books on electrical machine insulation design, evaluation, aging, testing and repair and was principal author of a number of Electric Power Research Institute reports on motor repair.

There are many wave and tidal devices under development but as yet very few are actually in revenue earning production. However, the engineering problems are gradually being solved and there is an appetite to invest in these renewable generation technologies for harsher environments. To some extent the wave and tidal generation industry is following in the wake of the wind industry, particularly learning from the growing experience of offshore wind farm deployment. This book combines wind industry lessons with wave and tidal field knowledge to explore the main reliability and availability issues facing this growing industry. Topics covered include; Overview of wave and tidal development Reliability theory relevant to wave and tidal devices Reliability prediction method for wave and tidal devices Practical wave and tidal device reliability Effects of MEC device taxonomy on reliability Availability and its effect on the cost of marine energy Wave and tidal device layout and grid connection Design and testing for wave and tidal devices Operational experience and lessons learnt Monitoring and its effect on operations and maintenance

Dieses Buch vermittelt einen Einstieg in die geophysikalischen Erkundungsmethoden Seismik und Gravimetrie. Es erklärt, wie elastische Wellen und Unterschiede der Gesteinsdichte zur Sichtbarmachung von Strukturen im Untergrund genutzt werden können. Das Kapitel Seismik erläutert zunächst die Elastizität von Gesteinen und die verschiedenen Typen elastischer Wellen und deren Ausbreitung. Es folgt eine Einführung in die digitale Verarbeitung seismischer Signale, in der die Konzepte der Fourier-, Z-, Radon- und Wavelet-Transformationen erläutert werden ebenso wie die Anwendung von Methoden der Konvolution, Dekonvolution, Kreuz- und Autokorrelation auf seismische Daten. Aufbauend auf diesen theoretischen Grundlagen erfahren Sie, wie mittels Durchschallung mit seismischen Wellen Strukturen des Untergrunds tomografisch sichtbar gemacht werden können. Hierauf folgt eine Einführung in die Techniken der Reflexions- und Refraktionsseismik die erläutert, wie die jeweiligen Datensätze bearbeitet, interpretiert und veranschaulicht werden. Das Kapitel Gravimetrie fasst zunächst zusammen, wie man Schwerebeschleunigungen aus Schwerepotenzialen berechnet und wie das optimal an das Schwerefeld der Erde angepasste Rotationsellipsoid definiert ist. Abweichungen hiervon sind die gesuchten Schwereanomalien, die Rückschlüsse auf Strukturen im Untergrund erlauben. Ihre Identifizierung erfordert eine Reihe von Korrekturen und Reduktionen, die ausführlich erläutert werden. Abschließend erfahren Sie, wie Schweredaten interpretiert werden können - vom Vergleich mit der Schwerewirkung einfacher Modellkörper über Fourier- und Wavelet-Analyse bis hin zu dreidimensionalen Modell- und Inversionsrechnungen. Dieses Buch eignet sich hervorragend als Lehrbuch für Bachelor-Studierende der Geophysik und der Geowissenschaften im Allgemeinen, sowohl zur Begleitung einer Vorlesung als auch zum Selbststudium. Aufgaben mit durchgerechneten Antworten helfen zur Überprüfung des erlangten Verständnisses.
