Generator Servicing, ATS Testing & Backup Power
Planned servicing, load testing, and fuel management ensuring generators deliver when power fails.
Why Generator Maintenance Prevents Failures
Generators passing weekly no-load test runs fail catastrophically during actual power cuts. Light-load running causes carbon buildup, incomplete combustion, and wet stacking. Cooling systems adequate for no-load operation overheat under full building load. Fuel systems deliver correctly at idle but starve engines under demand. Voltage regulators pass no-load tests but fail to maintain regulation when supporting real loads.
Annual load bank testing reveals hidden defects. Generators must operate at 50-100% rated capacity, forcing cooling systems, fuel delivery, and electrical output to design limits. Testing identifies alternator winding faults, governor speed control problems, fuel contamination, and cooling inadequacies before emergency use. Maintenance includes oil changes, filter replacement, coolant system servicing, and fuel quality management preventing failures during critical outages.
Comprehensive Maintenance Regime
Weekly & Monthly Checks
Weekly no-load test runs verify basic operation, check oil levels, coolant levels, and battery charge state. Monthly inspections include air filter condition, fuel water separators, belt tension, and exhaust smoke analysis. Visual checks identify leaks, corrosion, and component deterioration requiring attention before failures occur.
Cooling System Maintenance
Cooling systems prevent overheating under full load. Maintenance includes coolant testing for pH and glycol concentration, radiator cleaning, hose inspection, and thermostat testing. Failed cooling causes head gasket failure, cylinder scoring, and catastrophic engine damage. We pressure test systems, verify fan operation, and replace degraded coolant maintaining heat dissipation capacity.
Starting Batteries & Diesel Quality
Battery failures prevent starting during power cuts. We test battery voltage, load capacity, and charging system operation. Diesel fuel degrades through microbial growth and water contamination. Fuel polishing removes contamination, maintaining injector cleanliness and preventing fuel system failures. Annual fuel testing verifies quality for emergency use.
Transfer Switch Testing & Fire Compliance
Automatic transfer switches (ATS) detect mains failure and switch loads to generator supply. ATS testing verifies transfer occurs within specified time (typically 10 seconds), return transfer functions correctly, and interlocks prevent paralleling mains and generator. Failed ATS prevents backup power reaching building loads despite generator running correctly. We test mechanical operation, contact resistance, and control logic ensuring reliable switching.
Generator rooms require ventilation preventing carbon monoxide accumulation and fire suppression systems protecting critical infrastructure. We verify ventilation rates meet manufacturer specifications, inspect exhaust systems for leaks, and test fire detection linked to emergency shutdown. Fuel storage requires bunding and leak detection preventing environmental contamination. Compliance maintains safety and environmental standards.
