High voltage engineering is the study of power transmission at high voltages, in addition to the machinery utilized in high voltage transmission systems. High voltage electricity has sufficient potential to cause damage or harm. The main aim of transmitting power at high voltages is to improve efficiency. Furthermore, transmission of power at a high voltage decreases the loss and enhances the capability of the line, while extending the value of power transmitted across long distances. An understanding of the behavior of electrical insulating materials and dielectrics when exposed to high voltages of any kind including impulse, alternate current (AC) and direct current (DC) is fundamental to the study of high voltage engineering. The generation of test voltages necessitates the use of specialized current and voltage generators for impulse voltages, AC and DC. This book provides comprehensive insights on high voltage engineering. It is a vital tool for all researching and studying this field.
