This book covers the technology of switching in systems for electrical power transmission and distribution, from medium to (and including) ultra-high voltage for alternating current (AC). Emphasis is on the electrical aspects, covering the electrical transient phenomena of switching, its background, a generic description of equipment used for switching, various application examples, specification and commissioning of such equipment and testing aspects. The different methods to test high-voltage circuit-breakers are presented for each type o f switching condition. In order to be close to the use |
