Generator Load Bank Test Checklist

The generator is then step loaded with the load bank until the desired load level is reached.

Generator load bank test checklist. A load bank test ensures that your generator will run property when it s needed so that you can fully depend on it during an emergency situation. 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. During this two hour period the unit should be operated as follows. 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.

In more detail the process occurs in this manner. 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. Load bank testing for two continuous hours each year.

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. At 50 of the nameplate kilowatt rating for 30 minutes. 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. 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.

6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator. It verifies that all primary components of the generator set are in proper working condition. A generator load bank test involves an examination and assessment of a genset. Generally speaking you ll need to perform a weekly inspection and a monthly load test on your epss 8 4 1.

If a generator fails the monthly test it should be operated under a load supplied by a load bank i e. Standard load bank testing procedure. The load test on the generator shall be carried out increasing the load from 0 to 100 in steps of 25 using load bank. Duration of actual test varies based on type of test nfpa 110 and customer preference.

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.
