Emergency generators are external power sources that are kept onsite across many different industries to power operations in the event the main generator fails. Whether permanent or portable, emergency generators give companies peace of mind that their businesses are protected from unforeseen power issues.
However, backup generators cannot be simply left on standby until they are needed. Regular load bank testing is vital for ensuring emergency generators will perform correctly in the event of an emergency.
Read on to learn more about load bank testing, including how the process is conducted and why it is essential for reliable power system performance.
What Is Load Bank Testing?
Load bank testing is a way of assessing a UPS system's ability to perform correctly in the event of a power outage or power failure. The generator and Uninterrupted Power Supplies (UPS) are tested under load conditions to ensure they can provide sufficient and reliable power. The UPS connects the emergency generator with the equipment it protects for a continuous supply of energy.
Why Is Load Bank Testing Needed?
Typically, load bank testing is performed as a preventative maintenance service, which allows operators to assess the health of UPS batteries and replace individual cells when they no longer hold a charge or are close to failure.
Load bank testing also verifies that your generator maintains the proper pressure levels and temperature for safe operation. Conducting load bank testing allows issues to be identified and fixed early, preventing faults that could stop the generator from supplying reliable power during an outage.
How Is Load Bank Testing Performed?
The load bank is connected to the UPS or generator through suitable cables within a safe environment, away from sensitive equipment or personnel. Measurements are taken during discharge, where battery and system performance can be evaluated. A load bank test will identify problems with the generator and UPS and indicate the necessary remedial actions to fix the issue.
In the case of a standby generator, the system’s performance is assessed, including the ability of the generator to provide stable power, voltage stability, and the efficiency of control systems. The test also checks engine performance, fuel and oil pressure and the removal of engine deposits.
Professional Load Bank Testing
Load bank testing involves hiring load banks and qualified engineers to perform the test. While routine maintenance of power protection systems is essential, load bank testing must be carried out with extreme caution as it can temporarily reduce system resilience. Therefore, it's essential that the service is performed by trained professionals.
