Potential Transformer 1 The generator set functional test is a simplified test that can be performed to determine if the generator is functional. The generator set functional test should be performed on a generator set that is under load.The generator set functional test determines if the following statements happen:
A phase voltage is being generated.
The phase voltages are balanced.
The phase voltages change relative to engine speed.For more information on performing the generator set functional test, refer to Test and Adjusting , KENR5284.
