Switching in Electrical Transmission and Distribution Systems

Switching in Electrical Transmission and DistributionSystems presents the issues and technological solutionsassociated with switching in power systems, from medium toultra-high voltage.The book systematically discusses the electrical aspects ofswitching, details the way load and fault currents are interrupted,the impact of fault currents, and compares switching equipment inparticular circuit-breakers. The authors also explain all examplesof practical switching phenomena by examining real measurementsfrom switching tests.Other highlights include: up to date commentary on newdevelopments in transmission and distribution technology such asultra-high voltage systems, vacuum switchgear for high-voltage,generator circuit-breakers, distributed generation,DC-interruption, aspects of cable systems, disconnector switching,very fast transients, and circuit-breaker reliability studies.Key features:* Summarises the issues and technological solutions associatedwith the switching of currents in transmission anddistribution systems.* Introduces and explains recent developments such as vacuumswitchgear for transmission systems, SF6 environmental consequencesand alternatives, and circuit-breaker testing.* Provides practical guidance on how to deal with unacceptableswitching transients.* Details the worldwide IEC (International ElectrotechnicalCommission) standards on switching equipment, illustrating currentcircuit-breaker applications.* Features many figures and tables originating from full-powertests and established training courses, or from measurements inreal networks.* Focuses on practical and application issues relevant topracticing engineers.* Essential reading for electrical engineers, utility engineers,power system application engineers, consultants and power systemsasset managers, postgraduates and final year power systemundergraduates.
