Approaches to Arc Flash Hazard Mitigation in 600 Volt Power Systems by Curtis Thomas Latzo Pdf

ABSTRACT Federal regulations have recognized that arc flash hazards are a critical source of potential injury. As a consequence, in order to work on some electrical equipment, the energy source must be completely shut-down. However, power distribution systems in mission critical facilities such as hospitals and data centers must sometimes remain energized while being maintained. In recent years the Arc Flash Hazard Analysis has emerged as a power system tool that informs the qualified technician of the incident energy at the equipment to be maintained and recommends the proper protective equipment to wear. Due to codes, standards and historically acceptable design methods, the Arc Flash Hazard is often higher and more dangerous than necessary. This dissertation presents detailed methodology and proposes alternative strategies to be implemented at the design stage of 600 volt facility power distribution systems which will decrease the Arc Flash Hazard Exposure when compared to widely used code acceptable design strategies. Software models have been developed for different locations throughout a power system. These software model simulations will analyze the Arc Flash Hazard in a system designed with typical mainstream code acceptable methods. The model will be changed to show implementation of arc flash mitigation techniques at the system design level. The computer simulations after the mitigation techniques will show significant lowering of the Arc Flash Hazard Exposure.

Nuclear Power by Pavel Tsvetkov Pdf

Today's nuclear reactors are safe and highly efficient energy systems that offer electricity and a multitude of co-generation energy products ranging from potable water to heat for industrial applications. At the same time, catastrophic earthquake and tsunami events in Japan resulted in the nuclear accident that forced us to rethink our approach to nuclear safety, design requirements and facilitated growing interests in advanced nuclear energy systems, next generation nuclear reactors, which are inherently capable to withstand natural disasters and avoid catastrophic consequences without any environmental impact. This book is one in a series of books on nuclear power published by InTech. Under the single-volume cover, we put together such topics as operation, safety, environment and radiation effects. The book is not offering a comprehensive coverage of the material in each area. Instead, selected themes are highlighted by authors of individual chapters representing contemporary interests worldwide. With all diversity of topics in 16 chapters, the integrated system analysis approach of nuclear power operation, safety and environment is the common thread. The goal of the book is to bring nuclear power to our readers as one of the promising energy sources that has a unique potential to meet energy demands with minimized environmental impact, near-zero carbon footprint, and competitive economics via robust potential applications. The book targets everyone as its potential readership groups - students, researchers and practitioners - who are interested to learn about nuclear power.

Electric Distribution Systems by Abdelhay A. Sallam,Om P. Malik Pdf

This book provides a comprehensive treatment of electric distribution systems. Few books cover specific topics in more depth and there is hardly any book that deals with the key topics of interest to distribution system engineers. The book introduces these topics from two points of view: 1) The practical point of view by providing practical examples and the problems which can be solved. 2) The academic point of view where the analysis and various techniques used for distribution system planning are explained. The most outstanding feature of this book is a combination of practical and academic explanation of its contents. Another outstanding feature is a collection of the traditional and current topics of distribution systems condensed into one book. The reader will gain an understanding of distribution systems from both practical and academic aspects, will be able to outline and design a distribution system for specific loads, cities, zones, etc.. Readers will also be able to recognize the problems which may occur during the operation of distribution systems and be able to propose solutions for these problems.
