This book was released on 2011-06-24 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: This reference collects all relevant aspects electronic tap-changer and presents them in a comprehensive and orderly manner. It explains logically and systematically the design and optimization of a full electronic tap-changer for distribution transformers. The book provides a fully new insight to all possible structures of power section design and categorizes them comprehensively, including cost factors of the design. In the control section design, the authors review mechanical tap-changer control systems and they present the modeling of a full electronic tap-changer as well as a closed-loop control of the full-electronic tap-changer. The book is written for electrical engineers in industry and academia but should be useful also to postgraduate students of electrical engineering.

Download or read book Transformer Condition Control written by Vasily Ya. Ushakov and published by Springer Nature. This book was released on 2021-09-01 with total page 150 pages. 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.

This book was released on 1993 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Ferranti-Packard Resistor Transition Load Tap Changer is a relatively complex electrical/mechanical device consisting of drive systems and switch components enclosed in a self-contained oil filled steel compartment. This paper describes the components and operation of the tap changer and the changes and improvements made to it over the years and summarizes elements of the type test programs that were performed on full scale prototype tap changers.
Download or read book IEEE Standard Requirements for Tap Changers written by and published by . This book was released on 2012 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: This standard covers electrical and mechanical performance and test requirements for tap changers installed in voltage regulating power and distribution transformers of all voltage and kVA ratings. It covers load tap changers (LTCs), also known as on-load tap changers (OLTCs), which can change taps while the transformer is energized and carrying load; and it covers deenergized tap changers (DETCs), also known as off-circuit tap changers, which may be operated only while the transformer is not energized. For load tap changers, this standard covers both resistor and reactor types. It also covers certain aspects of the attendant tap changer motor-drive mechanism. It does not cover the tap changer control system (manual or automatic). Keywords: de-energized tap changers, IEEE C57.131, load tap changers, off-circuit tap changers, on-load tap changers, reactance type, reactor type, regulating transformers, resistance type, resistor type, step voltage, tap changers, taps, through current, voltage regulators.
