Generator Operation Procedure
Mar 13, 2018


1. Before start-up, check whether the quantity of fuel in the fuel tank is sufficient. There is no oil leakage in the oil pipes and joints. Whether the amount of cooling system water is sufficient, clean, no leakage, and whether the fan belt is tight. Check the internal combustion engine and the generator drive part should be connected reliably, the output line conductor insulation is good, the instrument is complete and effective.


2. After starting, it should run for 3 to 5 minutes at a low speed. After the temperature and oil pressure roller are normal, the operation can be started. There should be no abnormal noise in the speed increase of the generator, and the brushes on the slip ring and commutator should be in good contact with each other without jumping and sparking. Until the operation is stable, the frequency and voltage can reach the rated value before they can supply power to the outside.


3. When abnormal sound, odor, sudden rise in water temperature, and sudden drop in oil pressure occur during operation, stop the machine immediately to check and troubleshoot.


4. The generator power factor must not exceed the late phase (lag) of 0.95. The frequency range of variation must not exceed 0.5 Hz.


5. Shut off the main switch of each power supply shunt before shutting down, gradually reduce the load, then cut off the main switch of the generator power supply, and return the excitation varistor to the maximum position of the resistor, so that the voltage is reduced to the minimum value, and then the excitation switch and the switch are cut off. The point-to-point grounding switch finally stops the operation of the internal combustion engine.
