"As a reference handbook for all professionals and practising engineers associated with design, engineering, production, quality assurance, protection and testing. Project engineering, project design and project implementation. A very useful book for every industry for selection, installation and maintenance of electrical machines. For practising engineers, it would be like keeping a gospel by their sides. For In-house Training Programmes: A unique handbook for in house training courses for industries, power generating, transmission and distribution organizations. For students and research scholars: As a reference textbook for all electrical engineering students in the classrooms and during practical training. It can bridge the gap between the theory of the classroom and the practice in the field. A highly recommended book for all engineering colleges worldwide, right from first year through final year. It will prove to be a good guide during higher studies and research activities. Subjects like Earthquake Engineering, intelligent switchgears, SCADA Power Systems, surges, temporary over voltages, surge protection, reactive power control and bus systems etc. are some pertinent topics that can form the basis of their higher studies and research work. The book shall help in technological and product development and give a fresh impetus to R&D." (jacket). Bestandsnummer des Verkäufers 68242
