Load banks are used in generator load testing, verifying, and exercising a generator’s ability to handle an electrical load and are a key element in any backup power system.
Load banks can also provide automatic load sensing, where the load bank automatically adjusts to fluctuating power loads and keeps the generator running optimally. Global Power Supply offers new and used load banks in sizes from 100 kW and larger. We are an authorized dealer for several of the top load bank manufacturers in the industry.
Load Bank FAQs
What is a load bank?
A load bank is a device designed to simulate electrical loads to test and verify the performance of power sources like generators, UPS systems, and other electrical equipment under different conditions.
What are the types of load banks?
Load banks come in several types, including:
- Resistive Load Banks: Simulate resistive loads like lighting or heating.
- Inductive Load Banks: Mimic inductive loads such as motors or transformers.
- Capacitive Load Banks: Replicate capacitive loads often found in power factor correction systems. Many applications use a combination of these types.
Why is load bank testing important?
Load bank testing ensures your power systems perform reliably under real-world conditions. It helps identify issues like inefficiencies, overheating, or insufficient power output before they cause failure during critical use.
How do I choose the right load bank?
The right load bank depends on your specific requirements:
- Power Capacity: Match the load bank to the power system you’re testing.
- Application: Determine if you need resistive, inductive, or capacitive testing.
- Mobility: Choose portable units for on-site testing or stationary models for long-term use. Our team can guide you through the selection process.
What industries use load banks?
Load banks are used in various industries, including:
- Data centers
- Hospitals
- Telecommunications
- Military and defense
- Utilities and power generation
