Book Description
Presents current research into electromagnetic computation theories with particular emphasis on Finite-Difference Time-Domain Method This book is the first to consolidate current research and to examine the theories of electromagnetic computation methods in relation to lightning surge protection. The authors introduce and compare existing electromagnetic computation methods such as the method of moments (MOM), the partial element equivalent circuit (PEEC), the finite element method (FEM), the transmission-line modeling (TLM) method, and the finite-difference time-domain (FDTD) method. The application of FDTD method to lightning protection studies is a topic that has matured through many practical applications in the past decade, and the authors explain the derivation of Maxwell’s equations required by the FDTD, and modeling of various electrical components needed in computing lightning electromagnetic fields and surges with the FDTD method. The book describes the application of FDTD method to current and emerging problems of lightning surge protection of continuously more complex installations, particularly in critical infrastructures of energy and information, such as overhead power lines, air-insulated sub-stations, wind turbine generator towers and telecommunication towers. Both authors are internationally recognized experts in the area of lightning study and this is the first book to present current research in lightning surge protection Examines in detail why lightning surges occur and what can be done to protect against them Includes theories of electromagnetic computation methods and many examples of their application Accompanied by a sample printed program based on the finite-difference time-domain (FDTD) method written in C++ program

Book Description
This fourth edition of the text reflects the continuing increase in awareness and use of computational electromagnetics and incorporates advances and refinements made in recent years. Most notable among these are the improvements made to the standard algorithm for the finite-difference time-domain (FDTD) method and treatment of absorbing boundary conditions in FDTD, finite element, and transmission-line-matrix methods. It teaches the readers how to pose, numerically analyze, and solve EM problems, to give them the ability to expand their problem-solving skills using a variety of methods, and to prepare them for research in electromagnetism. Includes new homework problems in each chapter. Each chapter is updated with the current trends in CEM. Adds a new appendix on CEM codes, which covers commercial and free codes. Provides updated MATLAB code.

Book Description
This brief develops a data collection plan to assess loss related to electrical surges in homes, and explores the potential impact devices that prevent these surges could have in mitigating these losses. Key topics such as surge sources, surge effects and residential surge protection are clearly defined. Recent fire safety codes proposed a requirement that every dwelling unit be fitted with a surge protection device, as every year there is property damage to electrical and electronic equipment resulting from electrical surges. These proposals have not been implemented due to a lack of reliable data, which this brief seeks to change. The authors evaluate surge phenomena and their sources, surge protection methods, surge protection strategies and industry standards in order to present a data plan that can accurately assess loss related to electrical surges in homes.

Book Description
Although lightning protection has been practiced for more than 200 years, an exact numerical expression of protective effects has never been available. This is the first book to demonstrate the design of lightning protection equipment using numerical data of risk failure. Presents both theory and calculation methods for use in estimating the efficiency of lightning protection systems. It also serves as a guide for production of computer programs. Graphs and tables provide numerical data of the expected risk of shielding failures which can be used in design of lightning protection for transmission lines, high voltage overhead stations, buidings and other structures.

Book Description
Lightning Surge Analysis is one of major interest for electric utility companies. Particularly, for tall structure as EHV or UHV double-circuit towers, the surge characteristics become more dominant owing to the longer round-trip time of a traveling wave in the tower. In this book, the analysis of surge response have been carried out in the several arrangements. In all cases, the voltage measuring wire is placed at the perpendicular to the current lead wire. Each of the arrangement of the current lead wire affects the measured surge impedance of the vertical conductor and that has been explained details in this book. For the accurate analysis of lightning surge the Numerical Electromagnetic Code based on the Method of Moments is chosen, since it has been widely and successfully used in analyzing a tower system. Finally, this book presents some critical analysis concerning the simulation of electromagnetic transient in transmission lines caused by direct and indirect strikes of lightning, which will help the students, researcher and as well as relevant company to design the tower structure and protective device to protect various electric appliances that is used in our everyday life
