Emergency generator testing
Ideally, most emergency and standby generators are usually programmed to start on a weekly basis cycle, and they run for about one hour. The ability of the generator to produce electricity, circuit breakers, automatic transfer switch and voltage regulators are not tested since the starting system is of primary interest during the test.
It is important to know that two problems could compromise the reliability of an emergency generator and should be addressed to avoid future problems. They include:
• Under instances where the generator runs continually without load banking, diesel engines may develop wet stacking. Ideally, Wet stacking is a condition where condensed fuel and oil particles accumulate around the exhaust pipe, injector and valves of the engine. Usually, wet stacking reduces the efficiency of the generator making the engine to reduce its ability to generate the amount it’s supposed to produce.told us the problems which the generator could be having may not be known until it breaks down after some time. It is, therefore, important to carry out load banking to establish the full potential of your generator.
Load banking should be performed annually to your emergency generator to establish whether it’s underperforming or reaching its maximum potential. Whether you are using resistive or reactive testing, your load bank testing is dependent on your location, cable, load test personnel and the external power. If you are looking forward to having a successful load banking, you should take the four aspects into consideration. Failure to consider any of the factors may result in heavy fines, delay your schedule or even cause an injury.
Irrespective of the type of load bank testing procedure (resistive or reactive), load banks produces large amounts of heat and exhaust, and hence the test should be carried out in an open place where there is free flow of air.
