345 MVA Fully Water-Cooled Synchronous Condenser for Dumont Station Part II. Design, Construction and Testing

The paper describes the development of synchronous condensers using air and hydrogen as cooling mediums and the factors which led to the adoption of direct water cooling for the 345 MVA synchronous condenser for the Dumont Station of the American Electric Power System. Technical data, design and construction details and testing methods and results are presented.
