Download or read book FUNDAMENTALS OF FAULT CURRENT AND GROUNDING IN ELECTRICAL SYSTEMS written by HALDEN MORRIS & NORMAN CHAMBERS and published by Trafford Publishing. This book was released on 2014-06-30 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book seeks to explain in simple terms the behavior of fault current through the general mass of earth, the origin of short circuit current and its value, and how a circuit breaker operates. The drawings are unique and allow the reader to visualize the behavior of a fault current. The book clarifies common myths pertaining to a grounding electrode, short circuit, and opens neutral conditions, and provides an unambiguous understanding of the theoretical and practical explanation for an effective earthing and protective system in electrical installations. There are numerous grounding problems and unexplained fault conditions in electrical circuitry that are taken for granted and left unattended for extended periods. Potential voltage can be found on the earthing conductors in processing plants, refineries, and other industrial plants. A combination of topics in this book addresses problems that have been adversely affecting the electrical industry for years. There are a number of systems in the electrical industry that are common in the workplace but are not understood by the average workman who has to work with these systems daily. Systems such as ungrounded systems, clean earthing systems, motor controls, resistance grounding, lightning protection systems, and Intra earthing systems are all common systems; however, the knowledge base of these systems is very limited. This book highlights the basics of these topics and gives a working overview of these systems. The book also discusses the principle of operation of the ground fault circuit interrupter (GFCI). It is expected that the information provided will allow the reader to visualize various types of GFCIs and the principle of operation without necessarily having to revert to other text.

In recent years, offshore floating platforms have been frequently discussed in exploring deep-water resources such as oil, gas, and wind energy. This book presents step-by-step shipboard electrical system design and verification fundamentals and provides information on individual electrical devices and practical design examples, along with ample illustrations to back them. In addition, Shipboard Power Systems Design and Verification Fundamentals: Presents real-world examples and supporting drawings for shipboard electrical system design Includes comprehensive coverage of domestic and international rules and regulations (e.g. IEEE 45, IEEE 1580) Covers advanced devices such as VFD (Variable Frequency Drive) in detail This book is an important read for all electrical system engineers working for shipbuilders and shipbuilding subcontractors, as well as for power engineers in general.
Download or read book Electric Machines written by Hamid A. Toliyat and published by CRC Press. This book was released on 2017-12-19 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: With countless electric motors being used in daily life, in everything from transportation and medical treatment to military operation and communication, unexpected failures can lead to the loss of valuable human life or a costly standstill in industry. To prevent this, it is important to precisely detect or continuously monitor the working condition of a motor. Electric Machines: Modeling, Condition Monitoring, and Fault Diagnosis reviews diagnosis technologies and provides an application guide for readers who want to research, develop, and implement a more effective fault diagnosis and condition monitoring scheme—thus improving safety and reliability in electric motor operation. It also supplies a solid foundation in the fundamentals of fault cause and effect. Combines Theoretical Analysis and Practical Application Written by experts in electrical engineering, the book approaches the fault diagnosis of electrical motors through the process of theoretical analysis and practical application. It begins by explaining how to analyze the fundamentals of machine failure using the winding functions method, the magnetic equivalent circuit method, and finite element analysis. It then examines how to implement fault diagnosis using techniques such as the motor current signature analysis (MCSA) method, frequency domain method, model-based techniques, and a pattern recognition scheme. Emphasizing the MCSA implementation method, the authors discuss robust signal processing techniques and the implementation of reference-frame-theory-based fault diagnosis for hybrid vehicles. Fault Modeling, Diagnosis, and Implementation in One Volume Based on years of research and development at the Electrical Machines & Power Electronics (EMPE) Laboratory at Texas A&M University, this book describes practical analysis and implementation strategies that readers can use in their work. It brings together, in one volume, the fundamentals of motor fault conditions, advanced fault modeling theory, fault diagnosis techniques, and low-cost DSP-based fault diagnosis implementation strategies.

Download or read book Electrical Systems 2 written by Abdenour Soualhi and published by John Wiley & Sons. This book was released on 2020-04-14 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of diagnosis and prognosis play a key role in the reliability and safety of industrial systems. Failure diagnosis requires the use of suitable sensors, which provide signals that are processed to monitor features (health indicators) for defects. These features are required to distinguish between operating states, in order to inform the operator of the severity level, or even the type, of a failure. Prognosis is defined as the estimation of a systems lifespan, including how long remains and how long has passed. It also encompasses the prediction of impending failures. This is a challenge that many researchers are currently trying to address. Electrical Systems, a book in two volumes, informs readers of the theoretical solutions to this problem, and the results obtained in several laboratories in France, Spain and further afield. To this end, many researchers from the scientific community have contributed to this book to share their research results.

Download or read book Condition Monitoring of Rotating Electrical Machines written by Peter Tavner and published by Institution of Engineering and Technology. This book was released on 2020-06-04 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Condition monitoring of engineering plants has increased in importance as engineering processes have become increasingly automated. However, electrical machinery usually receives attention only at infrequent intervals when the plant or the electricity generator is shut down. The economics of industry have been changing, placing ever more emphasis on the importance of reliable operation of the plants. Electronics and software in instrumentation, computers, and digital signal processors have improved our ability to analyse machinery online. Condition monitoring is now being applied to a range of systems from fault-tolerant drives of a few hundred watts to machinery of a few hundred MW in major plants.
