Load testing involves applying a controlled electrical load to a generator to verify its performance, efficiency, and reliability. It simulates real-life demand to ensure the generator can handle actual load conditions.
Reliability Assurance: Confirms the generator starts and runs under load.
Identifies Weak Points: Detects issues such as overheating, fuel system problems, or voltage instability before an actual outage.
Compliance & Safety: Helps meet NFPA, ISO, or local code requirements (especially for healthcare and critical infrastructure).
Improves Lifespan: Running a generator under load helps prevent carbon buildup (“wet stacking”) in diesel engines.
Resistive Load Testing:
Uses resistors to create a load.
Simulates real-life loads like lights, heaters, and motors.
Ideal for most standard applications.
Reactive Load Testing:
Uses inductive or capacitive elements.
Simulates more complex electrical loads (e.g., motors with inrush current).
Important for generators used in industrial applications.
Automatic Load Bank Testing:
Load banks automatically simulate load conditions.
Often used for routine scheduled testing in larger facilities.
Pre-test inspection: Check fuel, oil, coolant levels, and electrical connections.
Load application: Gradually apply load in steps (usually 25%, 50%, 75%, 100%).
Monitor performance: Track voltage, frequency, temperature, exhaust, and fuel consumption.
Post-test analysis: Identify trends, anomalies, and maintenance needs.
