Power transformers are static devices transferring electrical energy between two circuits with separate systems of alternating voltages, by means of electromagnetic induction. They are used to connect power networks and components with different voltage levels. Transformers are essential components for the transmission, distribution, and utilization of electric power in large power grids, which are facing increasingly demanding requirements for power quality, integration of renewable sources and demand side management. Transformers benefit from the recent technological developments in components, design and construction.

High Voltage Power Transformers: State of the art and technological innovations describes the characteristics of design, manufacturing, and operation of large power transformers for high-voltage electrical networks, including autotransformers and shunt reactors. The topics covered include design solutions, criteria for the choice of main components (such as magnetic core, wires and windings, insulating parts, principal accessories), the aspects of dielectric, magnetic and thermal and noise requirements at specification, design and installation stages; moreover, the effects of DC components on converter transformers for VSC systems are dealt with.

The book provides information to assist readers in understanding and reducing risks in operation, and in taking advantage of opportunities arising from technological developments in transformer R&D for the emerging clean power system. It is particularly suitable for researchers and experts in academia, utilities and manufacturing, and advanced students in EE subjects.
