Download or read book Design Of Solid-state On Load Tap-changing For Transformer written by Nikunj Patel and published by LAP Lambert Academic Publishing. This book was released on 2012 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The on-load tap changing (OLTC) regulators have been widely used in various industry & power Application. They ensure a good regulation of the output voltage in presence of large variations of the input voltage with typical response time from several ms to several seconds. Earlier mechanical type of on load tap changers were into practice. But they had considerable limitations and drawbacks like arcing, high maintenance, service costs and slow reaction times. In order to overcome these limitations and drawbacks electronic (or solid-state) tap-changers were developed. The continuous growth of power semiconductor devices, such as the insulated gate bipolar transistor (IGBT), triac, thyristor, has allowed the development of fast OLTC regulators which has helped to fix other problems in the ac mains, like flicker and sags. The major idea in the solid-state-assisted tap changer is that solid-state switches with more control ability operate during the tap-changing process instead of mechanical switches which helps in reducing the arc during the tap-changing process.

Available in PDF, EPUB and Kindle. Book excerpt: What Is Solid State Transformer In actuality, an AC-to-AC converter, also known as a solid-state transformer (SST), power electronic transformer (PET), or electronic power transformer, is a type of electric power converter that replaces a conventional transformer in AC electric power distribution. This type of electric power converter is known as an AC-to-AC converter. Because it works at a higher frequency, this kind of transformer is more complicated than a traditional transformer that uses the utility frequency, but it also has the potential to be more space-efficient and smaller than a traditional transformer. The two primary varieties are referred to as "real" AC-to-AC converters and AC-to-DC-to-DC-to-AC converters, respectively. The AC-to-AC converter or DC-to-DC converter that is often found inside of a solid-state transformer is really a transformer. This transformer is what provides the electrical isolation and carries the entire power. This transformer is more compact because the DC-DC inverting stages that occur between the transformer coils are on the smaller side. As a result, the transformer coils that are needed to step up or step down voltages are also on the smaller side. Active regulation of voltage and current may be performed via a solid-state transformer. There are several that are able to convert electricity from single-phase to three-phase and vice versa. The amount of conversions that need to take place may be decreased by having variations that can either input or output DC power. This results in increased end-to-end efficiency. A Modular Solid-state transformer is similar to a Multi-level converter in that it is made up of numerous high-frequency transformers and has the same function. Because it is an intricate electrical circuit, it has to be constructed such that it can survive surges of various kinds, such as lightning. The solid-state transformer is a relatively new kind of transformer.

Available in PDF, EPUB and Kindle. Book excerpt: The J&P Transformer Book, 11th Edition deals with the design, installation, and maintenance of transformers. The book contains technical information, tables, calculations, diagrams, and illustrations based on information supplied by transformer manufacturers and related industries. It reviews fundamental transformer principles, the magnetic circuit, the characteristics of, and general types of transformers. The text contains tables showing the information that should be given to the transformer manufacturer to be used as a basis in preparing quotations. Transformer designs include three important distinct circuits to minimize losses: the electric, the magnetic, and the dielectric circuits. The book emphasizes that the maximum efficiency of any transformer occurs at the load at which the iron loss equals the copper loss. The text also discusses how the maximum overall operating economy of transformer substations, especially those with several transformers operating in parallel, can be effected by reducing the total transformation losses to a minimum under all loading conditions. The book is an essential reference for architects, system planners, or electrical engineers concerned with design, installation, and maintenance of transformers. It can also prove useful for electrical engineering students.
