Generator Load Bank Test Checklist

For gasoline powered natural gas powered or propane powered generators that do not meet the testing requirements outlined in 1 a above it will likely be necessary to add more load to the generator or conduct a load bank test to comply with testing requirements a load bank is typically a mobile piece of equipment that simulates the actual.

Generator load bank test checklist. O engine exhaust temperature during test if applicable p kw load under test q identification of unsatisfactory conditions and corrective action taken including parts replaced note. The generator is then step loaded with the load bank until the desired load level is reached. A generator load bank test involves an examination and assessment of a genset. The load test on the generator shall be carried out increasing the load from 0 to 100 in steps of 25 using load bank.

During this two hour period the unit should be operated as follows. If a generator fails the monthly test it should be operated under a load supplied by a load bank i e. The equipment used to conduct a load bank test produces artificial loads on the generator by bringing the engine to an appropriate operating temperature and pressure level. Generally speaking you ll need to perform a weekly inspection and a monthly load test on your epss 8 4 1.

The following is the basic step by step procedure for performing load bank testing on a generator set by utilizing a portable resistive load bank unit. 2 in lieu of nfpa 110 5 13 2 3 h i hook up the dry type load bank to generator and perform a stepped load test on the generator at 25 50 80 and 100 of the nameplate kw rating of the generator. At 50 of the nameplate kilowatt rating for 30 minutes. The key to a proper load bank test is that it tests your generator at its full kilowatt kw output rating.

At 25 of the nameplate kilowatt rating for 30 minutes. In more detail the process occurs in this manner. After the test the technician removes the load bank load first and transfers all switches back to the normal position before allowing the generator to cool down according to manufacturer guidelines. At 0 the run time shall be 5 mins for 25 10 mins for 50 10 mins for 75 3 hrs for 100 3 hrs.

Standard load bank testing procedure. And every 36 months you ll need to run level 1 epss systems for the amount of time specified in your application s class up to four hours of runtime 8 4 9 1 2. Load bank testing for two continuous hours each year. Duration of actual test varies based on type of test nfpa 110 and customer preference.

It verifies that all primary components of the generator set are in proper working condition.
