We are about to have a performance evaluation of our Cummins KTA50-32 Generator Set (Prime Power) rated at 1.25 Megawatt. This equipment did not have major overhaul for the last 15 years. Since the maximum stable load that can be provided at our sugar factory is only about 20% of the rated, (a) will the test give an accurate results on engine performance in terms of accurate horsepower output, engine operating temperature, cylinder compression pressure, etc? (b) If this is not acceptable, what is the best option that we can undertake in order to attain actual condition of the engine at present, in particular?
