National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Bradford Hydroelectric Inc., Ossberger Turbine Test.

DE84007079

Publication Date	1983
Page Count	397
Abstract	The performance analysis of a 708 hp Ossberger cross flow turbine installed at the Bradford Hydroelectric Station in Bradford, Vermont is described. Test data were obtained for both this unit and for a 1417 hp turbine at this site during a field test conducted on April 19-21, 1983 under the direction of the Alden Research Laboratory which has furnished the basic data for these tests. Stone and Webster was retained by FWE Stapenhorst, Inc. to witness the test and to perform an analysis of the test data for the purpose of estimating turbine performance for one of the turbines. This analysis, as discussed herein, is intended to account for losses in the generator, speed increaser and other equipment external to the turbine. Stone and Webster's analysis and the appendices, attached, indicates that for optimum control vane operation, the peak turbine efficiency for the 708 hp turbine lies within a band extending from 72.0% to 82.2%. The relatively large band width covers measurement tolerances and additional allowances for variations in determining the losses in equipment external to the turbine. (ERA citation 09:013460)
