Publisher's Synopsis
Electrical perspective it is well known that equipment such as light fittings, switches, motors or virtually any type of electrical apparatus may cause sparking or could generate In addition, static electricity built up on a person, clothing or item may discharge with a spark. In either case a spark could ignite an explosive atmosphere with potentially devastating results. Therefore if an explosive environment is unavoidable in a workplace, suitably rated and protected electrical equipment must be used to prevent the possibility of ignition from a spark, or other source of heat. In addition special precautions such as anti-static clothing and shoes may be necessary to prevent the possibility of a static electrical discharge potentially igniting a flammable gas or combustible dust. This comprehensive text gives students a strong foundation for an understanding of the behaviour, operation, and testing of electric power apparatus under normal, overload, and fault conditions. It provides up-to-date methods for preventive maintenance, presents logical methods by which the more common troubles may be identified and localized, and recommends emergency repairs that will keep the equipment in operation until it can be scheduled out for service. Also included are outlines of inspection programs that will help ensure safe, efficient, economical, and dependable operation.
