Download or read book Quality Confirmation Tests for Power Transformer Insulation Systems written by Behrooz Vahidi and published by Springer. This book was released on 2019-05-27 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on oil-paper insulation included in power transformers, especially for EHV and UHV transformers. The importance on insulation ever increased due to a growing voltage rating of transformers. Within the last decades, although research on the transformer insulation and diagnosis methods has advanced a lot, the insulation of HV transformers remained more or less unchanged. The book is divided into five chapters; the first and second chapters explain the basics of oil insulation, while the third chapter focuses on paper insulation. The final two chapters deal with the methods and outcome of testing both techniques. The primary target audience for this book is graduate students and power system engineers.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Bushings for Power Transformers, A Guide for Power Engineers There are number of good books on power transformers available in the marketplace and they go into much detail on the theories, designs, construction, components and testing of power transformers. However, they only devote one short chapter to bushings. Bushings are the most important component on your power transformer and one that is maybe least understood. This book will provide the Utility Power Engineer as well as the Utility Technician with a Handbook that will fast become the main reference tool when a bushing issue arises. For the Power Engineer who specifies new power transformers, it will become the go to handbook that will help them to avoid costly mistakes when specifying the bushings in their power transformer specification. This book will review the history of bushings for power transformers and will review the industry standards that apply to bushings. The book covers the different technologies used in bushing construction and will examine the techniques used in the selection of bushings for power transformers. It provides the basic information on bushing tests and how they relate to the power transformers. There is a chapter on maintenance and a guide for replacing bushings. The last chapter deals with a topic that occurs all too often, power transformer failures. This book provides a guide for investigating a power transformer failure when the bushing is suspect. The first hours after a failure is the most critical time help understand what caused the failure. This chapter will help the Utility reach the root cause of the event and hopefully prevent future failures. Every Power Engineer and Power Technician needs Bushings for Power Transformers in their bag of tools as they deal with their power transformers.
