Test a generator
The load bank tests a group to verify that it can still deliver its full power .
This is valid for any type of generator:
- A production / rental generator set . Here, it is a matter of ensuring the proper operation of the equipment let to each customer,
- An emergency generator, seldom used, seldom tested.
The full load test guarantees:
- the proper functioning of a generator
- its power handling , without cutting or disturbing the network by a real test.
This is because most failures and faults only manifest themselves at full load. A no-load test would not diagnose them, while further fouling the generator set.
Maintain a generator
Clean out the engine
An engine which runs after a long period at low load does not reach its optimum operating temperature. So there is a risk that it will get dirty: we use the term “ wet stacking ”. It is then necessary “flush” with a minimum of 80% of the nominal power .
Breaking in the engine
After having performed extensive maintenance, it is important to break in the engine using a test bank.
