The book provides a clear, systematic and exhaustive exposition of various discussions of High Voltage Engineering. Generation of a.c., d.c. and impulse voltage for testing of electrical equipments as per standard specifications have been explained. High voltage testing of some of the electrical equipments e.g. insulators, cables, transformers as per standard specifications has been explained. Various methods of non-destructive testing which yield information regarding life expectancy and long-term stability or otherwise of the insulating materials have been discussed. The book takes a view of various types of transients in power systems and suggests classical and more modern statistical methods of co-ordinating the insulation requirements of the system.
