Gas Turbine Generator Testing (FAT Test)

The gas turbine generator testing is performed after successful completion of the assembly at the manufacturing shop. 

Gas Turbine Generator Testing - Routine Testing List

1. Generator No-Load Current and Losses Test
2. Phase Sequence Test
3. Windings DC resistance measurement
4. Generator full load heat run (measurement of temperature rise and winding insulation resistance before and after heat run)
5. Full load wave analysis
6. Voltage and current phase balance
7. Rotor balancing test (during manufacture)
8. Overspeed test (120% for 2 min)
9. Overload test (110% for 2 hours)
10. Generator vibration measurement
11. Temperature rise test
12. Bearing temperature rise at no load and full load
13. Efficiency at 100% load, 75% load, 50% load at rated power factor
14. Generator sustained short circuit tests 
15. Dielectric tests
16. Windings insulation resistance test and voltage withstand test
17. Insulation resistance test on all windings heaters, RTD's. etc.
18. Test on batteries and chargers 
19. Tests on all auxiliary devices
20. Noise level tests

Generator Control Panels and Bus Ducts Tests

1. Dielectric test of main and auxiliary circuits
2. Test of mechanical operation
3. Test of electric operation of auxiliary circuits, check synchronizing, simulated auto/manual transfer sequence and interlocks, etc.
4. Voltage transformer and current transformer ratio and polarity check
5. Protection relay secondary injection
6. Bus-duct temperature rise test
7. Bus-duct high voltage test
