Available in PDF, EPUB and Kindle. Book excerpt: Large Power Transformers have long been a concern for the U.S. Electricity Sector, because the failure of a single unit can cause service interruption and lead to collateral damage, and there could be difficulties in quickly replacing them. This book assesses the procurement and supply environment of large power transformers (LPTs). Key industry sources have identified the limited availability of spare LPTs as a potential issue for critical infrastructure resilience in the United States, and both the public and private sectors have been undertaking a variety of efforts to address this concern. The following topics are examined in this book: characteristics and procurement of LPTs, including key raw materials and transportation; historical trends and future demands; global and domestic LPT suppliers; potential issues in the global sourcing of LPTs; and assessment of the risks facing LPTs.

Download or read book Bushings for Power Transformers written by KEITH ELLIS and published by Author House. This book was released on 2011-09-01 with total page 117 pages. 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.
