Diesel Gen-set Operation Instructions
53
2.2 Operation with load
If the Gen-set operate normally, let the Gen-set operate under rated speed for 3~5min
and close breaker after the Gen-set warms up to let the Gen-set operate under load. At
this time, inspect operating condition of the Gen-set. The main inspection items are as
follows:
1) Check speed and frequency of the Gen-set (normal speed and frequency of the
Gen-set is separately 1,500r/min and 50Hz). If speed and frequency of diesel engine
is lower than 1,500r/min or 50Hz, it need to adjust and lock throttle control handle to
increase speed of diesel engine to approximately 1,500r/min (frequency 50Hz);
2) Check voltage of three-phase output line of the Gen-set. Voltage of each line shall
be 400V;
3) Check three-phase current of the Gen-set and the measured current value shall not
exceed rated current of the Gen-set;
4) Check if water temperature and oil pressure of the Gen-set is normal or not. Water
temperature shall not be lower than 95 and oil pressure shall be higher than
℃
0.15Mpa;
5) Check if belched smoke is normal. Belched smoke of the Gen-set shall be colorless.
It is abnormal if large amount of black smoke, blue smoke or white smoke is belched
from this diesel engine.
Note: never increase load rapidly when coolant temperature is not higher than
60
