This book was released on 2013-10-21 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent Trends in the Condition Monitoring of Transformers reflects the current interest in replacing traditional techniques used in power transformer condition monitoring with non-invasive measures such as polarization/depolarization current measurement, recovery voltage measurement, frequency domain spectroscopy and frequency response analysis. The book stresses the importance of scrutinizing the condition of transformer insulation which may fail under present day conditions of intensive use with the resulting degradation of dielectric properties causing functional failure of the transformer. The text shows the reader how to overcome the key challenges facing today’s maintenance policies, namely: The selection of appropriate techniques for dealing with each type of failure process accounting for the needs of plant owners, plant users and wider society; and Cost-efficiency and durability of effect. Many of the failure-management methods presented rely on the fact that most failures give warning when they are imminent. These potential failures give rise to identifiable physical conditions and the novel approaches described detect them so that action can be taken to avoid degeneration into full-blown functional failure. This “on-condition” maintenance means that equipment can be left in service as long as a specified set of performance standards continue to be met, avoiding the costly downtime imposed by routine and perhaps unnecessary maintenance but without risking equally expensive failure. Recent Trends in the Condition Monitoring of Transformers will be of considerable interest to both academic researchers in power systems and to engineers working in the power generation and distribution industry showing how new and more efficient methods of fault diagnosis and condition management can increase transformer efficiency and cut costs.

This book was released on 2011-01-19 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, rapid changes and improvements have been witnessed in the field of transformer condition monitoring and assessment, especially with the advances in computational intelligence techniques. Condition Monitoring and Assessment of Power Transformers Using Computational Intelligence applies a broad range of computational intelligence techniques to deal with practical transformer operation problems. The approaches introduced are presented in a concise and flowing manner, tackling complex transformer modelling problems and uncertainties occurring in transformer fault diagnosis. Condition Monitoring and Assessment of Power Transformers Using Computational Intelligence covers both the fundamental theories and the most up-to-date research in this rapidly changing field. Many examples have been included that use real-world measurements and realistic operating scenarios of power transformers to fully illustrate the use of computational intelligence techniques for a variety of transformer modelling and fault diagnosis problems. Condition Monitoring and Assessment of Power Transformers Using Computational Intelligence is a useful book for professional engineers and postgraduate students. It also provides a firm foundation for advanced undergraduate students in power engineering.

Available in PDF, EPUB and Kindle. Book excerpt: This book is devoted to one of the main problems of modern electrical power engineering—power transformer diagnostics. The first three chapters discuss the fundamentals: The first chapter presents the physical reasons for power transformers’ failures and the technical and economic consequences of disruption of the normal operation. The second chapter reviews the standard technologies for monitoring the state of the high-voltage transformers. The third chapter tells about monitoring the condition of transformer windings based on the pulse method. The fourth chapter presents the technologies for transformer windings condition controlled by means of nanosecond pulses. The stages of improving the pulsed method based on a short probing pulse of the nanosecond range, the results of experiments on identifying the radial and axial displacements of the winding, studies of the effect of the duration and shape of the probing pulse on the sensitivity of the diagnostic procedure, and the stages of developing a mathematical as well as physical model of a power transformer are consistently presented.

Download or read book Optimisation of Online Condition Monitoring to Predict Power Transformer Failures in Distribution Networks written by Thabang Abel Motau and published by . This book was released on 2019 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: The stability of any distribution network is very much dependant on the performance of the power transformers. These transformers need to be monitored to ensure that any unwanted conditions, including high risk defects, are detected. The previous and current transformer failures in the Northern Cape Operating Unit show that the health status in the Plant Health Indicator of the transformers was on category A. Category A status means the transformers were healthy. The root causes of failure were that only some of the Dissolved Gas Analysis parameters were monitored. The transformers were shown to be healthy by the Plant Health Indicator at the time of the failure. Parameters such as cooling, bushings, tap changers, operating temperatures, ageing and loss of life were not monitored. The majority of transformer failures recorded were affected by the parameters mentioned above, of which some are not monitored in the Plant Health Indicator. This research study discusses the application of integrated online condition monitoring for power transformers as one of the techniques to assess the condition of the power transformer during operation. The integrated online condition monitoring allows for transformer condition assessment without having to switch off the transformer, thereby minimising power supply interruptions. The integrated online condition monitoring system is unique technology that monitors the condition of various parameters of the power transformer such as the cooling fans, on-load tap changer, bushings, transformer operating temperatures, dissolved gas analysis, transformer ageing and loss of life. The research design is quantitative with data analysis retrieved directly from the online condition monitoring server. The results from the bushings, cooling fans, tap changer and temperatures form part of the analysis. Data analysis lead to a discussion of these parameters, which highlights the problems currently experienced with transformer failures in the Northern Cape Operating Unit. The research study revealed that, although Eskom is having the best maintenance practices in power transformers, there is a need to improve and save costs, as the current maintenance strategies of power transformers are expensive. The results of the study should be regarded as exploratory, and provide directions to researchers for further, more in-depth studies in this field. The cost analysis was performed over a period of ten years, as compared to the current costs of maintenance/monitoring and asset replacement strategies of power transformers. The total saving per year was a great benefit for tasks such as inspections/maintenance/monitoring and asset replacement. This was validated by the results from the proposed transformer online monitoring technology that can predict the defects which may result in catastrophic transformer failures.
