This book, now in its second edition, presents a comprehensive exposition of the basic principles involved in the analysis and computation of power system transients using a statistical approach. The book deals with probability distribution of switching overvoltages in overhead lines, underground cables, and machine windings. The accuracy of statistical methods for power system transients, including the suitability of Gaussian distribution for these methods, is discussed. In the case of overhead lines, a simplified statistical method for estimating the phase-to-phase risk of insulation failure is explained.
This book Useful for engineering students.
