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.

The book provides a clear, systematic and exhaustive exposition of various aspects of Generation Distribution and Utilization of Electrical Energy. The modern distribution network is spread over a large geographical area and hence the concept of distribution automation has been discussed so as to operate the system with a higher index of reliability and more economically. Various aspects of utilization viz. electric heating and welding, illumination engineering, and electrolytic processes are included. Modern trends in electric traction, viz. the role of SCADA in electric traction and automation in electric traction are discussed in great detail.

This book provides a clear, systematic and exhaustive exposition of the various dimensions of electrical power systems, both at basic and advanced levels, explained and illustrated through solved examples. This book covers: fundamentals of power systems, line constant calculations and performance of overhead lines; mechanical design of lines, HVDC lines, corona, insulators and insulated cables; voltage control, neutral grounding and transients in power systems; fault calculation, protective relays including digital relays and circuit breakers; power systems synchronous stability and voltage stability; insulation coordination and over voltage protection; modern topics like load flows, economic load dispatch, load frequency control and compensation in power system; state estimation in power systems, unit commitment, economic scheduling of hydrothermal plants and optimal power flows; and zbus formulation, power transformers and synchronous machines as power system elements. It includes large number of solved examples, practice problems and multiple choice questions. With all these features, this is an invaluable textbook for undergraduate electrical engineering students and practicing engineers.
