Product description

The new edition of this useful and practical handbook is a guide to the use of induction motors for electricity generation in remote locations and arises out of the practical experience of manufacturers and installers of induction generators working in village locations in a number of countries. The use of motors as generators is now well proven and promises to be an important element in establishing self-sustaining local capacity for village-scale hydro in developing countries. Micro-hydro is a valuable source of energy for rural industries and village electrification schemes. It offers potential to remote communities with applications in village lighting, mechanized food processing, and the supply of power to small-scale industrial activities.
