In a typical arrangement, the uninterruptible power supply is located between the power sources and the protected loads. This is designed to protect the loads from damage that may result from unexpected power failures. This is why uninterruptible power supplies, or UPS, are so important – and why testing them to ensure proper performance before an actual power outage occurs is so crucial. The best way to do this is through load bank testing.

How are Load Bank Tests Performed?

To perform load bank testing, quality-rated cables should be connected to the load banks to ensure optimal connection and energy transfer. Load banks are made up of both heating elements and fans to offset that heat and keep the unit cool. Therefore, the load bank units should be allowed ample space so that temperature and noise fluctuations do not impact the results or create issues with alarms or sprinkler systems. Likewise, they should not be located too close to people who are actively working – but should be placed no further than twenty meters away from the UPS systems.

During discharge, measurements are taken to measure the performance of the electrical system including the UPS and generator plant. If problems are detected, steps can be taken promptly to address them.

What Information Can a Load Bank Test Offer?

In addition to drawing attention to any maintenance that may need to be performed, regular load bank testing will offer information about the following:

  • The proficiency of the generator’s engine
  • Oil and fuel pressure
  • Stable frequency
  • Efficiency of all control systems
  • Proficiency of the generator’s alternator
  • Overall system performance

The Importance of Load Bank Testing

Why is it so important to regularly perform load bank testing? If you consider the importance of your backup generator, you’ll understand the need for routine maintenance via testing. Load bank tests allow you to stay on top of maintenance and perform repairs or replacements before issues become too serious. Likewise, they prevent these problems from causing more severe issues during emergencies.

If you don’t like the idea of being caught with a malfunctioning UPS or generator during an emergency scenario, keep up with your load bank testing.
