The method to determine the real useful power of the unit is: multiply the rated power of the diesel engine for 12 hours by 0.9 to obtain a data (kw). If the rated power of the generator is less than or equal to the data, the rated power of the generator is determined as the real useful power of the unit. If the rated power of the generator is greater than this data, this data must be used as the real useful power of the unit.
While the method the mentioned can provide an estimate of the real useful power of a diesel generator, it is not a reliable or accurate method for determining the actual real useful power of the unit. This is because it assumes that the generator will operate at full load for 12 hours, which is not always the case in real-world scenarios.

By performing a load bank test, you can determine the actual real useful power
To check the real useful power of a diesel generator, you need to perform a load bank test. This test involves connecting a load bank to the generator and applying a load to the generator that is equal to its rated output. The load bank simulates the actual load that the generator would experience in operation, allowing you to measure the generator’s performance under real-world conditions.
Here are the steps to perform a load bank test on a diesel generator:
- Connect the load bank to the generator according to the manufacturer’s instructions.
- Start the generator and allow it to warm up for several minutes.
- Set the load bank to the rated output of the generator.
- Monitor the generator’s voltage, frequency, and amperage readings.
- Allow the generator to run at full load for at least 30 minutes.
- Monitor the generator’s performance during the test, including any fluctuations in voltage or frequency.
- Record the generator’s performance data, including voltage, frequency, and amperage readings.
- Compare the recorded data to the manufacturer’s specifications to determine if the generator is operating within acceptable limits.
Performing a load bank test is an important part of maintaining a diesel generator and ensuring that it is capable of providing reliable power when needed. It is recommended that load bank tests be performed at least once a year to ensure that the generator is operating at peak performance.
