Capacitive load banks

Leading power factor load banks, ideal for industrial applications

We provide a fleet of capacitive load banks to simulate electronic and non-linear loads during testing. 

Routinely used in utilities, data centers, and other industrial settings, capacitive load banks use capacitors store and deploy electric loads. With a leading power factor, they’re an effective way to conduct load testing while counteracting inductive loads or bringing power factors closer to unity.

At Aggreko, we provide a comprehensive range of capacitive load banks, alongside specialist expertise and engineering excellence, so you can:

  • Counteract inductive loads by applying capacitive load
  • Test equipment with a specific amount of kVAR
  • Correct power factors and make them closer to 1/unity
  • Test equipment under fluctuating loads, which may be a closer reflection of your real-world loads

FAQs about Aggreko’s capacitive load banks

A capacitive load bank is a device used to simulate electrical loads that have a leading power factor, typically found in systems that involve the use of capacitor banks or in applications with high-frequency electronics. Capacitive load banks are used to test and verify the performance of power systems, such as generators or UPS systems, to ensure they can handle capacitive loads effectively. This type of testing is critical for industries where power factor correction or high-tech equipment is in use.

Capacitive load banks are primarily used in industries and applications that involve high-frequency electronics, capacitive power factor correction, or renewable energy systems. Common applications include:

  • UPS systems: To verify that the system can handle the leading power factor generated by capacitive loads.
  • Power factor correction equipment: To test the performance of power capacitor banks designed to improve the power factor in electrical systems.
  • Renewable energy systems: Capacitive load banks can be used to simulate loads in wind and solar energy systems where variable power factors are common.
  • High-frequency electronics: In industries such as telecommunications, data centers, or semiconductor manufacturing, where capacitive loads are prevalent.

Capacitive load banks ensure that your energy systems can manage complex loads without performance degradation or failure.

A capacitive load bank works by applying a leading power factor load to an energy source like a generator or UPS system. It mimics the conditions that occur when capacitors or high-frequency electronics are part of the load, testing how well the system can manage this type of demand. 

During the test, the load bank monitors key performance indicators such as voltage, current, and power factor. By simulating these conditions, capacitive load banks help identify any potential weaknesses in the system’s ability to handle reactive power and ensure reliable operation in real-world conditions.

 

Capacitive load bank testing is essential for ensuring that energy systems can handle leading power factors and maintain voltage stability. Without proper testing, systems may experience:

  • Voltage instability: Leading power factor loads can cause voltage spikes or fluctuations, which may damage sensitive equipment or lead to downtime.
  • Overheating of components: Without proper load management, systems under capacitive load conditions may overheat, causing premature wear or failure.
  • Reduced efficiency: Energy systems that cannot handle leading power factors may operate inefficiently, wasting energy and increasing operational costs.

Regular capacitive load testing ensures that your energy system is ready to manage these challenges, improving both reliability and efficiency.

Aggreko’s capacitive load banks offer several advantages, including:

Capacitive load banks are essential for testing systems that use power factor correction (PFC). PFC systems are designed to improve the efficiency of electrical systems by reducing the phase difference between voltage and current, which improves the power factor.

Capacitive load banks simulate the leading power factor typically corrected by PFC systems. Testing with these load banks ensures that your PFC equipment is performing as expected and that your electrical system maintains a high power factor under varying load conditions. This leads to more efficient energy use, reduced operational costs, and enhanced system stability.

The frequency of capacitive load testing depends on your specific energy system and operational requirements. However, regular testing is recommended:

  • For critical systems: Annual testing is essential for systems that are crucial to operations, such as UPS systems in data centers or hospitals.
  • After upgrades or repairs: If you have made any modifications to your energy system, testing should be performed to ensure the system can handle the new load conditions.
  • Before commissioning new equipment: Capacitive load testing is vital before bringing new systems online to verify their ability to handle the required load.

Routine testing helps identify potential issues early, ensuring your systems remain reliable and efficient under all load conditions.

Yes, capacitive load banks are often used in renewable energy testing, particularly in systems that generate DC energy and convert it to AC using inverters. In renewable energy setups, such as wind or solar energy, the power factor can vary based on weather conditions or system performance. Capacitive load banks help simulate these conditions, ensuring that inverters and other equipment can manage fluctuating power factors without voltage instability or inefficiency. This type of testing is essential for ensuring the reliability and efficiency of renewable energy systems.
