Field testing of gas turbines, compressors, reciprocating engines and other machineries has become increasingly common due to the need to “Verify Efficiency, Power, Fuel Flow, Capacity and Etc” to ensure optimized performance and evaluation of machine’s condition.

The performance test in the field is often necessary to assure that it meets the “Performance Predictions and Guarantee Customer’s Return on Investment”. Economic considerations demand that the performance and efficiency be verified at the actual field site. The field environment is not ideal and measurement uncertainties are necessary to characterize the validity of a performance test.
