Why Load Banks Are Essential for Your Next Project

Jul 17, 2024

Many teams exercise standby generators under no-load conditions, which can present an engine problem when you need to utilize the generator during power outages. Load bank testing is an effective solution for testing your power system and detecting any issues that could prevent you from completing tasks and achieving operational efficiency.

Any application needing electrical power warrants a load bank, including ground power units, battery systems, inverters, engine generators and auxiliary power units.

The Role of Load Bank Testing and Operation

Load bank testing validates battery autonomy and operational performance by testing the generator and battery system under several load conditions. You can use load bank testing to identify power system faults to ensure your system is reliable.

Power supply systems need this periodic testing to ensure they’re capable of handling loads when the need arises. Along with testing the power system’s components, load banks bring several other benefits, including eliminating wet slacking, ensuring proactive maintenance and meeting regulatory compliance for some power generation applications.

There are two main types of load banks:

Resistive load bank: Resistive load banks are common across several industries because they provide generator and prime mover equivalent loading. The role of resistive load banks is to test a generator and prime mover at complete capacity. This type dissipates the energy you apply and can simulate pure resistive loads, such as heating or lighting.
Reactive load bank: Contrary to resistive load banks, reactive load banks have either capacitive loads or inductive loads. This type gradually dissipates sudden power increases, which can be ideal for applications expecting abrupt surges. You can add capacitive loads to have a leading power factor, where the current leads the voltage. Alternatively, inductive loads can reduce the power factor to less than unity, where the current lags behind the voltage. Reactive loads can simulate the operating conditions teams experience in the field. Applications with non-linear loads often employ reactive loads.

Load Banks Across Various Industries

There are many industry applications for load banks. While main industries include electrical contracting, mining, construction and utility, opportunities exist outside of these landscapes. Some examples of applications for load banks across industries include:

Power sector: Emission compliance testing, load rejection testing, solar power quality testing, wet stacking prevention in diesel engines, prime power application generators, fault detection, and prime power application load optimization
Defense and aerospace: Generator maintenance and commissioning, ground equipment power testing, and load optimization
Telecommunication: Generator commissioning for the power grid
Industrial automation: Load rejection testing and turbine and diesel generator testing
Data centers: Air conditioning power supply and compliance testing

When it comes to building applications, you may consider the value of load bank testing as opposed to building load testing. While both can be effective, load bank testing has several advantages of building load testing — though it’s important to note that load bank testing may not detect issues elsewhere in the building.

For instance, load bank testing is more reliable because interruptions can occur during building load testing when transferring the load to the generator from the utility. Additionally, load bank testing creates a safe and controlled environment, reducing the likelihood of damage or accidents.

While building load testing introduces risks such as excessive stress on equipment, overheating and electrical faults, load banks have safety features and measures to minimize risks, safeguarding equipment and workers.

How Load Banks Help Project Efficiency and Performance

Load banks are crucial for ensuring power supply reliability, but they also employ several other benefits to projects. These solutions can help meet project goals and contribute to project efficiency.

Load Banks Help Engines

Guaranteeing standby generator availability: Load banks ensure your equipment can handle primary utility power losses and allow you to continue working on tasks without disruption.
Verifying battery charge: A common failure point for generator sets is a lack of battery charge. You can prevent this issue by using a load bank to ensure batteries can initiate an engine start.
Reaching appropriate operating temperatures: Load banks help engines reach the proper temperatures necessary for efficient operation and burn unburned fuel contamination or residue.
Promoting preventive maintenance: Using load banks lets you detect issues early, ensuring you can deliver preventive maintenance to keep your equipment and systems running while avoiding costly future repairs or unnecessary downtime for extensive repair or replacement services.

Unlocking Cost Savings With an Industrial Load Bank

An additional benefit and result of using load banks is cost savings. In a landscape of rising costs, finding ways to reduce costs and maintain cash flow is essential.

Load banks empower you to extend equipment life spans and minimize downtime with proactive maintenance. By delivering essential care before minor issues cause significant problems, you can save money by avoiding expensive repairs and losses associated with unnecessary downtime.

In some industries, avoiding downtime is a critical matter of saving lives, such as health care. In other industries, just a few minutes of downtime can lead to millions of dollars in financial loss, like customer service. There can also be regulatory compliance issues in those moments offline.

You can rent load banks to save on operational costs further and ensure efficiency even during uncertain times. Furthermore, using load banks rather than constructing physical loads allows you to save on expenses associated with expertise, labor and materials. You can rent load banks to reduce setup time and ensure your team can dedicate more time to the testing process rather than the installation process of another solution.
