Load Bank Testing


Rapid Power carries several Load Banks that can handle any situation. From portable units for small generators to trailer-mounted units for large units. Load bank testing is a preventive maintenance practice required for all standby power systems. The main purpose of this testing is to help ensure the generators reliable operation during utility power failure.

Why do Load Bank Testing?

As per CSA 282 09 Load Bank Testing is required on initial start-up and as a part of your regular maintenance schedule. Simply put, there are two major reasons to scheduled Load Bank Testing.

1) Load Bank Testing is a real-life trial of how your generator will perform when it is needed when you are expiring a loss of power, this will allow a realistic diagnostic of all your systems and components and is the first step in diagnosing any potential likely malfunctions.

ONLY Load Bank Testing will verify performance of:

  • Coolant Problems
  • Radiator Functionality
  • Ensure Generator Performance
  • Meet Requirements For Risk Management
  • Identify Wet Stacking

2) The second reason Load Bank Testing is required is to eliminate the potential of Wet Stacking. Wet Stacking is a condition where burnt fuel and carbon deposits build up in the exhaust system producing smoke and unnecessary pollution. A generator that does not on a full load will not reach optimal running temperature and as a result will not burn-off unused fuel and carbon deposits in the exhaust system.

Carbon Deposits will form on:

  • Injectors
  • Pistons
  • Rings
  • Turbo Chargers
  • Valves
  • Lubrication Oil

As a result of carbon deposit build-up you will experience:

  • Reduced Performance
  • Reduced Engine Life.
  • Cooling System Failure

Without testing your generator on full-load, there will be no way to successfully determine that the generators cooling system can handle large loads without overheating. Another important fact to consider is without your generator reaching optimal temperature, unburned diesel fuel will remain in the exhaust system – this becomes a major fire hazard.

How Rapid Powers Load Bank Testing Works?

As per CSA C282 09, your emergency generator is subject to an annual 2 hour full-load test. With that said, most of our customers opt for semi-annual load testing to minimize Wet-stacking and ensure their generator is fully operation when they need it most.

We will create a custom maintenance schedule for you based upon the type of generator, demand load, frequency of operation and other key factors that determine how often and at what load, your generator should be Load Bank Tested.

Our Load Bank Testing does not result in an interruption of power. We provide an unparalleled level of technical support by utilizing our trained personnel to oversee testing. We supply the load bank, cables and a certified technician who will conduct the test safely and efficiently.

Upon completion of each Load Bank Test, we will provide you with a certificate for presentation for the fire department officials. We will also deliver a full report of the readings. This will include your equipment’s activity including generator output readings such as voltage, amperage, KW amount, etc. Our comprehensive report will highlight any unusual occurrences, recommended remedial work, or suggested upgrades.
