This book has been written based on PhD thesis. In this book, most
fundamental dimensional analysis technique is used to develop some
mathematical relationships to understand the flashover mechanism of
contaminated insulator. The expression of time to flashover, flashover
voltage in terms of ESDD and surface conductivity has been developed. In
addition, the relationships between leakage resistance and ESDD, and
ESDD and wind velocity have been developed. All mathematical models have
been verified by the experiments.
