Manual on Induction Motors Used as Generators : A Publication of Deutsches Zentrum für Entwicklungstechnologien — GATE A Division of the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) GmbH

is a Swiss electro-mechanical engineer specialized in the design 01 hydraulic machinery and equipment. He worked in industry both at home and abroad for over ten years. In 1981, he established his own company of consulting engineers, mainly engaged in energy and water supply projects. He has designed and implemented around 20 micro-hydropower plants ranging from 0,5 to 450 kW power output. His engagement in development cooperation includes short term consultancy missions for hydropower projects in Asia and the Caribbean, the organization of training courses for hydropower engineers and other contributions to programmes 01 technology transfer. Jacques Dos Ghali, is a senior lecturer at the Swiss Federal Institute 01 Technology in Lausanne. After ten years in industry (electrical power stations and networks) he was appointed to the electricity department of the Federal Institute of Technology in 1970. His activities in the field of micro-hydropower include the developmentof an electronic load controller and lectures on electrical engineering for hydropower training courses. His involvement in development cooperation is mainly in the field of energy planning, the establishment of master plans and education programmes, and the implementation of electric laboratories in universities and technical colleges in various countries in Africa. Peter Eichenberger has been working with J.-M. Chapallaz, Consulting Engineers since 1990. He has a background in civil engineering and hydraulics, and spent a number of years with other Swiss civil engineering consultants mainly on rural development projects. Prior to joining J.-M. Chapallaz, he worked as a senior development adviser in a pump lift irrigation project in Sumatra, Indonesia. Gerhard Fischer is a German mechanical engineer specialized in hydraulic machinery and governing systems. After graduating from the Institute of Hydraulic Machinery in Stuttgart, he spent six years as a research er there, working on improved turbine and governor designs for both industrialized and developing countries. In 1988, he joined J.-M. Chapallaz, Consulting Engineers where he cooperated in the design of micro-hydropower plants and turbines. He carried out various short-term consultancy missions for development aid projects in Africa, the Caribbean and Columbia.
