Index Testing—Relative Turbine Performance

by Jeffrey A. Judd, GE, Minneapolis, MN, USA,

Document Type: Proceeding Paper

Part of: Waterpower '85


The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head are not measured but are determined relatively for various gate settings. The intent of this paper is to present a basic, economical form of Index testing. It lists some of the situations in which Index testing should be considered, looks at pre-test preparations, and takes a brief look at both test procedures, and test results.
