Bharat heavy electricals limited (bhel) is the largest engineering and manufacturing enterprise of its kind in india...started manufacturing switchgears in 1961 and has since made significant strides in the field. Dr rene peter paul smeets kema high power laboratories, the netherlands handbook of switchgears is the effort of 22 experts from bhel at publishing, in one volume, a comprehensive work on switchgear design, application, and protection. The book is a detailed guide to both, the requirements of conventional low voltage switchgears, as well as the technological aspects of medium and high voltage switchgears. It also provides information on gis, high voltage circuit breakers, auto reclosers/sectionalisers, instruments transformers, surge arresters, control and interlocking schemes, and energy metering. The handbook further addresses the issue of protection of switchgears, including protection schemes for medium voltage switchgears, generator protection for large generators, ehv transmission system control and protection, and integrated protection and control systems for sub stations. The erection, commissioning, operation and maintenance aspects of switchgears under various conditions are also included, with experience based information on the dos and don ts of site work, inspection, and maintenance procedures. With its coverage of general concepts as well as consolidated information in the context of indian conditions, this book is an essential reference for all practicing switchgear engineers, institutions, and academicians. - from Amzon
