The Benefits of Load Bank Testing
Load banks provide a substitute load onto the UPS or generating set and any associated LV switchgear, cabling and maintenance bypass systems. Load banks are normally of the resistive power type and are self-contained cabinets with internal cooling and ventilation to allow heat into the environment. Load banks are normally placed outside of a building with temporary power cables run to the location of the power system to be tested.
Testing using a load bank provides important benefits for a critical power installation:
- Provides a means to increase the kW load on a system using set increments
- Integrity tests the power protection system installation using a simulated load
- Allows problems to be rectified and prevents expensive downtime or load damage
- Tests the installed runtime capacity and duration (UPS batteries or generator)
- Test the ability of the generator to start-up in a timely manner and clears carbon deposits
- Provides the facility to run a generator at full power and temperature
- Provides the opportunity to compare historical performance data for a variety of readings including: kW load, amperage, AC voltage, frequency and oil pressure
The load bank normally delivered and installed by a specialist logistics team, with the temporary power cables installed and connected by our power engineers. The load bank testing itself is arranged to coincide with the commissioning or maintenance of the UPS system or generating set. Load bank testing can be used for Site Acceptance Testing (SAT) during commissioning, Factory Acceptance Testing (FAT) or as part of annual preventative maintenance routines.
