Fundamentals of High-Voltage Engineering
Prof. Ravindra Arora and Dr. Bharat Singh Rajpurohit
The subject of “High Voltage Engineering” is basically study of the condition of 'electrical insulating materials' in order to estimate their performance under high electrical stress over the life span of installations under different physical conditions. The lectures in this course covers with simple and systematic approach meant for students, teachers and practicing engineers.
The fundamentals of High-Voltage Engineering exist in understanding the behaviour of dielectrics, the electrical insulating materials, subjected to high voltage of any kind, ac, dc and impulse. Without the insulation system, the electricity cannot exist. Our Earth has a unique property of absorbing electricity and yet maintain its zero potential. Hence, it can be said that the electrical insulation system is the base of power system. This renders a responsibility to the electrical power engineers to understand the performance of insulation system under all possible conditions in a better way.
This course has a novel approach in describing the fundamental concept of “field-dependent behavior of dielectrics” when subjected to different types of high voltages. The contents begin with a systematic classification of electric fields and the techniques of field estimation. In-depth coverage of performance/behaviour of gaseous, solid and liquid dielectrics has been made in this course. The basics of high voltage laboratory techniques, non-destructive testing, measurement of high test voltages and dielectric properties are also covered in detail.
Course Contents:
Course contents are evolved over the lectures in classrooms involving active interaction and discussions with the students. Course content is able to cover the syllabus of all major Institutions/Universities in India and abroad.
