Download or read book Recent Trends in the Condition Monitoring of Transformers written by Sivaji Chakravorti and published by Springer Science & Business Media. 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.

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 114 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.
