Load Bank Testing
Our Service Offerings
Comprehensive load bank testing to verify the performance and capacity of your generators. We ensure that your backup power systems are ready to perform when needed.
VarcoMac's Load Bank Testing services provide crucial verification of your generator's actual performance capabilities under controlled load conditions. Unlike routine no-load tests, our comprehensive load bank testing applies precise electrical loads to thoroughly evaluate your generator's true capacity and identify potential issues before they lead to failures during actual emergencies.
Our professional load bank testing includes:
- Capacity Verification: We systematically test your generator at various load levels up to 100% of rated capacity, confirming it can actually deliver the power output specified without performance degradation or overheating.
- Graduated Loading Protocols: Our testing follows manufacturer-recommended procedures with staged loading patterns that progressively increase electrical load in precise increments, allowing proper engine conditioning and monitoring of response at each stage.
- Extended Duration Testing: We conduct extended running periods at full load to verify sustained performance capabilities, identifying issues like cooling system limitations that only appear during prolonged operation.
- Performance Parameter Monitoring: Throughout testing, we continuously monitor critical parameters including voltage stability, frequency regulation, oil pressure, coolant temperature, exhaust temperature, and fuel consumption to identify any anomalies.
- Controls and Transfer Switch Verification: Our comprehensive testing includes verification of generator control systems, monitoring functions, and automatic transfer switch operations to ensure complete system integration.
- Wet Stacking Prevention: For diesel generators, our load bank testing eliminates harmful unburned fuel accumulation (wet stacking) that commonly occurs during no-load or light-load operation, improving reliability and extending engine life.
The VarcoMac difference includes detailed documentation of all test results with comprehensive analysis and specific recommendations to address any identified issues. Our testing equipment includes multiple portable load bank units allowing us to test generators from small standby units to multi-megawatt systems. Regular load bank testing is not just good maintenance—it's essential for confirming your emergency power system will perform as expected when needed most. With VarcoMac's professional load bank testing services, you gain documented verification of your generator's actual capabilities and the confidence that comes from knowing your backup power system has been thoroughly proven under controlled conditions.
