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. Key Features: * Electric Stress Estimation and Control using various techniques. * Mechanism of breakdown of gases, liquids and solid insulating materials. * Application of insulating materials for different electrical equipments. * Generation of high a.c., d.c. and impulse voltages and currents for testing of electrical equipments. * Various techniques and circuits for measurements of high voltages. * Testing procedures for testing of insulators, cables transformers, circuit breakers etc. * High Voltage Schering Bridge and partial discharge measurement techniques for assessing life expectancy of equipments. * Insulation coordination and over-voltage protection. * Photo plates to give a physical feel of various equipment in a high voltage laboratory. * Large number of solved examples, practice problems and multiple choice questions.
