Common Problems Of Standby Generators

When there is electricity cut off, then the first thing that comes to your mind is Generator. Domestically, generators may not be a necessity but when it comes to businesses then generators are needed. Generators allow to keep the power supply uninterrupted and for some businesses, this is very critical. For example, a vast manufacturing unit producing thousands of units daily cannot afford a single power outage because it will be costly. But there can be another problem arises, that they have a backup generator and suddenly all load shifted to the generator, the generator malfunctioned or unable to take the complete load. Before that instance, no one has ever tested that generator on full load or there may be some problem in the generator that was identified till that day. This can be a terrible position because arranging the backup for standby generators on short notice is not easy and then the complete plant will be shut down. Even incidents like these can cost serious financial losses. The best way to keep checking the health of your generators and must be aware of the common problems of standby generators, so they can be minimized. There are few tests like generator load bank testing or reactive load bank, that can help to know about the health of generators. Some of the common problems of the standby generators are;

  1. The first thing to know about a standby generator is its age. The performance of the aging generator will not be a new one. Especially in the case of the load test, the old generator will not be performing at par. The generator load bank testing become important if you have an aging generator because you need to keep testing the performance of your aging generator at full load. Even reactive load bank test can also tell the performance of your generator 
  2. When the generators are not in frequent use, then there is the chance that a problem has been arising inside but due to no utility, that problem hasn’t been identified. This is the common problem among the less used generators and time if need, they are unable to perform. Reactive load bank test helps to identify such issues beforehand, even if the generator or generators are not in frequent use, even then load back testing or resistive load bank test should be done regularly. This will help to know about any persistent problem and to avoid any surprise at the time of need.
  3. Wet stacking is a common problem in standby generators. The standby generators are not in frequent use and due to which there can be residual fuel or lube get stacked in the exhaust. If they were not removed for a longer period, it may affect the performance of the generator. During the generator load back testing, the issue of wet stacking can easily be addressed.
