| Review: |
Lightening and switching surges are the most frequent causes of power-system outages. In order to design reliable systems, engineers need to understand the basics of generation and propagation of electromagnetic transients and how they can be avoided. This student textbook covers these basic theories and describes electromagnetic transients in power systems and the problems that the power industry is currently trying to solve. It discusses power-system grounding, lightning-induced voltages on overhead power lines, protection of substations and transients in low-voltage systems with emphasis on power-electronic systems, all of which are very important. The new edition has been updated and revised and a new chapter on dynamic overvoltages has been added. |
