商品簡介
This reference and textbook presents the latest developments in power system insulation coordination, emphasizing the achievement of optimum insulation strength at minimum cost. It reviews factors of power transmission reliability, such as strike distances or clearances, arrangement and number of insulators, and use of overhead ground or shield wires; assesses phase-ground and phase-phase clearances, supplemental tower grounding, and substation shielding; evaluates insulation strength, traveling waves, line arresters, and induced overvoltages; compared new insulation methods with those outlined in IEEE and IEC guides; highlights sources of stress such as lightning, switching, temporary overvoltages, and normal power frequency voltage; considers operation of devices to reduce stress, such as surge arresters and closing resistors in circuit breakers; and more.
