Generator Maintenance
Maintaining and testing of diesel generators and their associated switchgear is critical to ensure reliable operation during power outages. Here’s our guide to performing these tasks:
Diesel Generator Testing and Maintenance
1. Routine Inspections
- Fuel System: Check fuel levels, inspect for leaks, and ensure the fuel is not contaminated.
- Oil Levels: Verify oil levels and quality. Change oil as per manufacturer recommendations.
- Coolant System: Inspect coolant levels, hoses, and radiator for blockages or leaks.
- Air Filter: Check for clogs or dirt accumulation and replace if needed.
- Battery System: Test voltage levels, clean terminals, and check electrolyte levels.
2. Functional Tests
- Automatic Transfer Switch (ATS): Simulate a power outage to ensure the generator automatically starts and switches the load to the generator.
- Emergency Stop Test: Verify that the emergency stop mechanism works correctly.
Switch Maintenance (Switchgear and ATS)
1. Visual Inspection
- Look for signs of corrosion, overheating, or physical damage.
- Check for loose connections or damaged insulation.
2. Cleaning
- Use appropriate tools to remove dust, dirt, and debris.
- Ensure switchgear components are free from oil or moisture.
3. Electrical Testing
- Insulation Resistance Test: Ensure proper insulation resistance to prevent electrical faults.
- Contact Resistance Test: Measure resistance across switch contacts to detect wear or damage.
- Overcurrent/Undervoltage : Verify protection devices are functioning correctly.
4. Functional Testing
- Simulate operation of the switchgear to ensure smooth engagement and disengagement.
- Test ATS switching from utility to generator and back.
By following a regular schedule for diesel generator and switch maintenance, you can ensure reliability, minimize downtime, and extend the equipment’s lifespan.
