Generator testing using AC load banks

Regular maintenance
Wet stacking occurs predominantly with under loaded gen-sets that are used in prime power applications. By using a load bank, as part of any regular maintenance routine, will provide the generators an essential health check and prevent diesel engine failure due to wet stacking. 

Wet stacking
Wet stacking occurs due to the lightly loading ( at levels of less than 35% for a prolong time period ) of a genset.   The consequence of low loading results in wet un-burned fuel deposits building up in the engine cylinders. This fuel residue over time will line the combustion chamber cylinders and cause a reduction of the engines performance rating and efficiency which will ultimately cause premature failure of the generator. 

As part of the regular maintenance it is recommended that the genset is loaded in incremental steps with due consideration of the age and service history of the genset is given prior to  loading at 100%

Running the generator on loads above 35% of the genset rating will allow the engine to reach the recommend operating temperature, which will burn off the choke deposits.
