Book Description
Learn how to ensure optimal efficiency! Save money, resources -- and downtime -- with this invaluable reference that can help you evaluate and improve transformer efficiency in electric power systems more reliably. The author, a professional electric system efficiency expert, clearly explains the typical causes of poor efficiency in transformer-load and no-load losses. He reviews traditional efficiency improvement methods, such as the use of larger conductors and properly sizing transformers, as well as effective new solutions, including the use of amorphous steel and cryogenics, laser-etched silicon steel, and advanced design transformers. This is relevant, ready-to-use information that should be interest to any cost-conscious commercial and industrial engineer manager.

Book Description
Section 161 of the Energy Policy Act of 1992 (EPACT) encourages energy-efficient federal procurement. Executive Order 12902 and FAR section 23.704 direct agencies to purchase products in the upper 25% of energy efficiency. Agencies that use these guidelines to buy efficient products can realize substantial operating cost savings and help prevent pollution. As the world's largest consumer, the federal government can help pull the entire US market towards greater energy efficiency, while saving taxpayer dollars. The efficiency levels in this Recommendation are the same as those in NEMA's TP-1 standard. Additionally, the EPA/DOE ENERGY STAR{reg_sign} program identifies efficient low-voltage distribution transformers with the ENERGY STAR{reg_sign} label. Complying models meet the same efficiency criteria specified in this Recommendation (and TP-1).

Book Description
Energy-Efficient Electrical Systems for Buildings offers a systematic and practical analysis and design approaches for electrical distribution and utilization systems in buildings. In addition to meeting the minimal safety requirements set by the National Electrical Code (NEC), the design approach consider the life-cycle cost analysis of designing energy efficient electrical distribution systems as well as integrating renewable energy technologies into both residential and commercial buildings. The book first provides a general overview of basic power systems commonly available in buildings. Then, detailed discussions of various components of typical building electrical distribution system are outlined through several chapters including transformers, protection devices, conductors and conduits, power and lighting panels, and motor control centers. The book includes several illustrations and numerous examples and analysis exercises are included, along with detailed design examples.

Book Description
The improvement of electrical energy efficiency is fast becoming one of the most essential areas of sustainability development, backed by political initiatives to control and reduce energy demand. Now a major topic in industry and the electrical engineering research community, engineers have started to focus on analysis, diagnosis and possible solutions. Owing to the complexity and cross-disciplinary nature of electrical energy efficiency issues, the optimal solution is often multi-faceted with a critical solutions evaluation component to ensure cost effectiveness. This single-source reference brings a practical focus to the subject of electrical energy efficiency, providing detailed theory and practical applications to enable engineers to find solutions for electroefficiency problems. It presents power supplier as well as electricity user perspectives and promotes routine implementation of good engineering practice. Key features include: a comprehensive overview of the different technologies involved in electroefficiency, outlining monitoring and control concepts and practical design techniques used in industrial applications; description of the current standards of electrical motors, with illustrative case studies showing how to achieve better design; up-to-date information on standarization, technologies, economic realities and energy efficiency indicators (the main types and international results); coverage on the quality and efficiency of distribution systems (the impact on distribution systems and loads, and the calculation of power losses in distribution lines and in power transformers). With invaluable practical advice, this book is suited to practicing electrical engineers, design engineers, installation designers, M&E designers, and economic engineers. It equips maintenance and energy managers, planners, and infrastructure managers with the necessary knowledge to properly evaluate the wealth of electrical energy efficiency solutions for large investments. This reference also provides interesting reading material for energy researchers, policy makers, consultants, postgraduate engineering students and final year undergraduate engineering students.

Book Description
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.
