Book Description
Electric Field Analysis is both a student-friendly textbook and a valuable tool for engineers and physicists engaged in the design work of high-voltage insulation systems. The text begins by introducing the physical and mathematical fundamentals of electric fields, presenting problems from power and dielectric engineering to show how the theories are put into practice. The book then describes various techniques for electric field analysis and their significance in the validation of numerically computed results, as well as: Discusses finite difference, finite element, charge simulation, and surface charge simulation methods for the numerical computation of electric fields Provides case studies for electric field distribution in a cable termination, around a post insulator, in a condenser bushing, and around a gas-insulated substation (GIS) spacer Explores numerical field calculation for electric field optimization, demonstrating contour correction and examining the application of artificial neural networks Explains how high-voltage field optimization studies are carried out to meet the desired engineering needs Electric Field Analysis is accompanied by an easy-to-use yet comprehensive software for electric field computation. The software, along with a wealth of supporting content, is available for download with qualifying course adoption.

Book Description
Numerical methods for solving boundary value problems have developed rapidly. Knowledge of these methods is important both for engineers and scientists. There are many books published that deal with various approximate methods such as the finite element method, the boundary element method and so on. However, there is no textbook that includes all of these methods. This book is intended to fill this gap. The book is designed to be suitable for graduate students in engineering science, for senior undergraduate students as well as for scientists and engineers who are interested in electromagnetic fields. Objective Numerical calculation is the combination of mathematical methods and field theory. A great number of mathematical concepts, principles and techniques are discussed and many computational techniques are considered in dealing with practical problems. The purpose of this book is to provide students with a solid background in numerical analysis of the field problems. The book emphasizes the basic theories and universal principles of different numerical methods and describes why and how different methods work. Readers will then understand any methods which have not been introduced and will be able to develop their own new methods. Organization Many of the most important numerical methods are covered in this book. All of these are discussed and compared with each other so that the reader has a clear picture of their particular advantage, disadvantage and the relation between each of them. The book is divided into four parts and twelve chapters.

Book Description
Recent research relating high-voltage transmission line electric field spatial uniformity to transmission line power capacity and switching overvoltage susceptibility underscored the need for a better method to calculate critical flashover voltage and the need for better overvoltage data to quantify insulation margins for transmission design. This dissertation includes two manuscripts documenting research addressing these needs. Research in the first manuscript extends the finite-difference time-domain method with dynamic corona losses to multiphase transmission lines with bundled subconductors. The model is adapted for practical use in high-volume statistical transient simulation. Results highlight the importance of considering detailed overvoltage profiles and accounting for corona losses when seeking to carefully quantify insulation design margins. The second manuscript reports development of a new method for efficient computation of three-dimensional electric fields due to high-voltage transmission lines and nearby space charge modeled as a finite group of point charges. The approach is based on the charge simulation method and uses Fourier principles to discretize conductor charge densities and reduce matrix inversion computations. Analysis of three-phase transmission lines with multiple subconductors per phase can have more than a hundredfold reduction in computational burden compared to typical charge simulation methods performed entirely in the spatial domain. This improvement allows subconductors to be modeled individually, giving greater flexibility to experiment with simulated bundle configurations. The method is used to model the phase-to-phase breakdown process between bundled conductors in high voltage transmission lines. The model includes leader and streamer space charge and all image charge effects. Analysis using the method demonstrates that switching impulse critical flashover voltage can be estimated based on the ability of the leader-streamer system to survive minimum electric field conditions during propagation between electrodes. This means that it is often unnecessary to model complete bridging of the air gap to estimate critical flashover voltage. A practical design example of a cross rope suspension transmission structure demonstrates the effectiveness of the method for ongoing research into a more cohesive approach for electrical design of transmission lines using the correlation between electric field spatial nonuniformity, transmission line power capacity, and switching overvoltage susceptibility.

Book Description
The book is written for students as well as for teachers and researchers in the field of High Voltage and Insulation Engineering. It is based on the advance level courses conducted at TU Dresden, Germany and Indian Institute of Technology Kanpur, India. The book has a novel approach describing the fundamental concept of field dependent behavior of dielectrics subjected to high voltage. There is no other book in the field of high voltage engineering following this new approach in describing the behavior of dielectrics. The contents begin with the description of fundamental terminology in the subject of high voltage engineering. It is followed by the classification of electric fields and the techniques of field estimation. Performance of gaseous, liquid and solid dielectrics under different field conditions is described in the subsequent chapters. Separate chapters on vacuum as insulation and the lightning phenomenon are included.
