Description
New Age International High Voltage Engg by C L Wadhwa
The book provides a clear, systematic and exhaustive exposition of various dimensions of high voltage engineering. Generation of AC/DC and impulse voltage for testing of electrical equipment's as per standard specifications have been explained. High voltage testing of some of the electrical equipment's e.Br>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 system 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 equipment's. Generation of high AC/DC and impulse voltages and currents for testing of electrical equipment's. 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 equipment's. Insulation coordination and over voltage protection. A few photo plates to give a physical feel of various equipment's in a high voltage laboratory. Large number of solved examples, practice problems and multiple choice questions.
