Load Banks
Discover how resistive load banks, inductive load banks, and reactive load banks enhance the reliability and efficiency of power generation systems through comprehensive load bank testing.
Efficiency and Reliability with Our Advanced Load Banks
Load banks play a crucial role in optimising power generation systems, ensuring they operate at peak efficiency. By simulating real-world load conditions, they provide reliable load testing and maintenance solutions, enhancing system performance and longevity. Our resistive load banks and combined load banks support various applications, from UPS systems to generator service.
Advantages of Load Banks
Load banks are essential for testing and maintaining power systems, ensuring reliability and efficiency. By using resistive load banks, inductive load banks, and reactive load banks, you can simulate real-world electrical loads to prevent failures and optimise performance.
Reliable Power Testing
Load bank testing verifies the performance of generators, UPS systems, and power systems under controlled conditions, ensuring reliability during a power outage
Preventative Maintenance
Regular load bank testing helps prevent failures by detecting issues early. Portable load banks allow for quick, efficient testing without disrupting operations.
Optimised Efficiency
By simulating real electrical loads, load banks improve the efficiency of power equipment. Our load bank range supports generator service and transfer switch testing for seamless operation.
Types Of Load Banks
Load banks come in different types, each designed to simulate specific electrical conditions. Here are some common ones:
Use Cases For Load Banks
Load banks are essential for testing, commissioning, and maintaining power systems across many industries. Load banks ensure your backup power is reliable when it matters most. Here are some of the most common use cases:
Manufacturing sites require accurate electrical performance during high-demand operation. Load banks test 50kVA to 1000kVA generators used to power industrial equipment.
They help verify:
- Reliable load-testing capacity
- Voltage and frequency stability under heavy demand
- Correct power factor for production machinery
- Optimised fuel efficiency during sustained operation
This keeps production running efficiently and reduces downtime risk.
Telecommunications infrastructure needs consistent, clean backup power. Load banks test 10kVA to 500kVA generators that support towers, network hubs and relay sites.
Testing checks:
- Voltage rating under fluctuating loads
- Frequency stability
- Efficient fuel consumption
- Power factor performance for sensitive electronics
This reduces risk of service interruptions and improves system resilience.
Load banks help test inverters, batteries and hybrid renewable systems by applying controlled loads that match real site demand.
They support setups interfacing with 10kVA to 500kVA generators to confirm:
- Voltage and frequency stability
- Smooth energy discharge and transfer
- Accurate power factor behaviour
- Reliable load-testing capacity for new installations
Ideal for commissioning and system optimisation.
Hospitals require uninterrupted, compliant backup power. Load banks test emergency generators ranging from 10kVA to 1000kVA to ensure critical systems remain protected.
Testing verifies:
- Stable voltage and frequency output
- Correct power factor under medical load conditions
- Proper fuel efficiency during extended operation
- Reliable response for life-support and emergency equipment
This maintains compliance and safeguards patient safety.
During commissioning, load banks replicate the electrical demand required by HVAC systems and backup generators, from 10kVA up to 1000kVA units.
Testing ensures:
- Correct voltage regulation
- Stable frequency range
- Accurate power factor under simulated building load
- Full load-testing capacity before systems go live
This helps detect issues early and guarantees performance once the facility is operational.
Marine vessels depend on stable power for propulsion, navigation and onboard systems. Load banks simulate operational loads on 10kVA to 1000kVA marine generators.
Key outcomes:
- Proper voltage rating and clean frequency output
- Prevention of wet-stacking
- Improved fuel efficiency
- Verified load-handling capacity at the vessel’s required power factor
This ensures reliable power performance in all marine conditions.
Mining operations rely on high-capacity generators in remote, demanding environments. Load banks allow safe, controlled testing across 50kVA to 1000kVA generators.
Testing helps validate:
- Voltage stability under peak load
- Accurate frequency control
- Efficient fuel burn under different load levels
- Compliance with mining electrical requirements
This prevents unexpected downtime and ensures systems operate at the correct power factor for heavy machinery.
Load banks help data centers verify that backup generators and UPS systems can support full demand during an outage. They simulate realistic electrical loads across 10kVA, 50kVA, 100kVA, 500kVA and 1000kVA generators.
This testing confirms:
- Stable voltage rating under load
- Correct power factor performance
- Reliable frequency range control
- Safe load-testing capacity for critical systems
The result is improved reliability, reduced risk of overload and better fuel efficiency during emergency operation.
