The diesel generator set must be operated by personnel who are familiar with the unit structure and master the safety operation procedures. New or newly overhauled diesel units shall undergo 60 hours of running in as required, and necessary maintenance shall be done.

Before the new or long-term unused generator is put into normal operation, it must undergo strict inspection, mainly to check the winding insulation, wiring, etc. if there is any inconsistency, it shall be handled as necessary.

After starting the diesel engine, the speed shall be increased slowly. On the premise of checking and confirming that everything is in good condition, the no-load operation from low speed to rated speed can be carried out. During no-load operation, focus on checking the oil pressure, abnormal noise, excitation current, three-phase voltage change, etc. in case of any abnormality – stop the machine immediately for inspection. Find out the situation before starting. If everything is normal, it can be put into normal operation. The operator shall closely monitor the changes of the instruments on the control panel, whether they are within the allowable range, and make corresponding adjustments.

During operation, operators shall keep a safe distance from live equipment and wear labor protection equipment. Pay attention to the sequence of switching operation. In case of power failure, disconnect each branch switch first, then disconnect the main switch, and then switch the position of four pole double knife switch. During power transmission, the sequence is reversed. During normal shutdown, part of the load shall be unloaded first, then the main switch shall be turned off, and finally the diesel engine shall be turned off. It is not allowed to cut off the power automatically with the diesel engine flameout. Conduct routine inspection on the unit after shutdown and record the operation (work diary).

In case of electric shock, the power switch shall be cut off quickly, or the power supply shall be cut off or disconnected from the power supply quickly with insulating appliances. Then carry out rescue and ask a doctor to come to the scene for rescue. In case of electrical equipment flood, the relevant power supply shall be cut off immediately and reported to the local power supply station, and then the fire shall be put out. Dry fire extinguishers and carbon dioxide fire extinguishers shall be used for fire fighting of live equipment, and water is not allowed.
