This book is written based on my M. Sc. Engineering thesis. The method uses a set of closed loop transfer functions, one for each synchronous machine and derived by taking Laplace transformation of the machine s nonlinear swing equation in a tricky way. The transfer function directly takes into account the time of fault clearing and the changes in the maximum electrical power output of the machine due to changes in the prefault network topology during and after clearing the fault. The earliest possible location of the root of the characteristic equation (the denominator of the transfer...

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.
