What is a Load Bank?

A load bank is a device that creates a sustainable electrical load safely. The load is applied to a power source to validate system design performance and capacity under any operating condition.

What Type of Load Banks are Available from ComRent?

• Resistive Load Banks to mimic the operational load that a power source will see in actual use
• Reactive Load Banks to provide a lagging load to accurately simulate electric motor start up and pump function
• Capacitive Load Banks to provide a leading power factor to compensate for power factor correction on the utility

What are the Differences Between Load Bank Testing and Plant Load Testing?

The most critical differences between load bank testing and plant load testing are scheduling flexibility, load sustainability and testing duration.

Load banks do not rely on plant availability; therefore, are able to offer power-on-demand when you need to test. A load bank's primary function is to deliver a sustainable power load to enable full capacity system testing for short and prolonged periods of time.

Why is Load Testing Important?

Load bank testing will save you time and money in the long run. It is how you determine the operating status of your primary power systems. It’s also how you exercise backup systems to ensure they will be available when called upon. Load testing at start-up and during commissioning and maintenance will detect problematic conditions before they escalate and cause downtime.

What Problems Can Load banks Detect?

Load banks detect a wide range of conditions that could threaten a power system. Defective equipment, design errors, flawed construction, emissions, natural aging, improper settings on system control components and the negative effects of underutilization are among the problems load bank testing can detect before they cause a power disruption.

Why Should I Rent a ComRent Load Bank When I Can Purchase My Own?

Renting a load bank frees you from the maintenance and warehousing costs of owning the equipment. Technical and compliance consultants are another expense saved by renting from ComRent. It also saves time. We'll manage the equipment, logistics and technical support details that are part of every testing project, freeing you to focus on other areas.
