Generator Load Bank Testing Procedure

Standard load bank testing procedure.

Generator load bank testing procedure. 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. The recommended procedure to follow for the load bank test would be to. 6 4 4 1 1 2 specifies that the 10 second criterion does not apply during the monthly testing of the generator. Load bank testing for two continuous hours each year.

Monthly load testing of at least 30 of the nameplate rating for 30 minutes for diesel powered emergency power supplies eps see nfpa 110 2010. During this two hour period the unit should be operated as follows. Generator engine and load bank testing outline a. Start and run the generator until the water temperature stabilizes.

Generator load bank testing is an examination and assessment of genset. The equipment is used to load the bank test to produce an artificial load on the generator by bringing the engine at the appropriate temperature and pressure level. It verifies that all components of a generator are in proper working conditions. 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.

8 2 4 3 if a generator fails the monthly test it should be operated under a load supplied by a load bank i e. 8 4 9 1 ec 02 05 07 ep5 and ep6. It verifies that all primary components of the generator set are in proper working condition. Generator load bank testing what you need to know about the procedure for many companies having a standby generator is important in keeping crucial services operating in times of an outage.

At 25 of the nameplate kilowatt rating for 30 minutes. Remove the load bank load first after the test. Duration of actual test varies based on type of test nfpa 110 and customer preference. A generator load bank test involves an examination and assessment of a genset.

The test verifies that the generator is capable of handling incrementally higher kw loads that it is still capable of accommodating its maximum specified load and that it can work for an extended period of time. 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. Step load the generator with the load bank until the desired load is reached. Load bank testing shall be performed for a period of four 4 hours at the full rated load of the generator and witnessed by a county representative.

Salt water brine tank load banks are not acceptable for this purpose and are disallowed and will not be utilized for this test. Transfer all manual or automatic transfer switches to the emergency source.
