Load Bank For Generator Testing

The frequency schedule for load bank testing on a generator often depends on how the generator is classified and what it is a standby for.

Load bank for generator testing.

A load bank is a piece of electrical test equipment used to simulate an electrical load to test an electric power source without connecting it to its normal operating load. Load bank testing involves firing up a standby or prime power generator and running it under an artificial load at its maximum capacity for a specified period of time. The testing for an annual load bank test and the triennial exercise may be combined according to nfpa 110 2010. Load bank testing involves firing up a standby or prime power generator and running it under an artificial load at its maximum capacity for a specified period of time.

During testing adjustment calibration or verification procedures a load bank is connected to the output of a power source such as an electric generator battery servoamplifier or photovoltaic system in place of its. It verifies that all components of a generator are in proper working conditions. For example if a generator is used as a backup for services associated with loss of life or serious injury such as in a hospital setting the testing requirements are much more frequent. Step load the generator with the load bank until the desired load is reached.

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. 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. Remove the load bank load first after the test. Load bank testing for two continuous hours each year.

Generator load bank testing is meant to ensure your backup source of power remains reliable and provides maximum performance when needed. During load bank testing data can be recorded that offers a more thorough look into the health of the gen set on the whole. Start and run the generator until the water temperature stabilizes. This is important for.

During this two hour period the unit should be operated as follows. Generator load bank testing refers to a process to assess a generator s capabilities verifying all genset components are in optimal working condition under different loads. Transfer all manual or automatic transfer switches to the emergency source. 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.

The recommended procedure to follow for the load bank test would be to. At 25 of the nameplate kilowatt rating for 30 minutes.
