Monthly Diesel Generator (DG) Checks: Ensuring Optimal Performance

Regular maintenance is essential for diesel generators to function efficiently, especially in industries where power reliability is critical. This blog outlines the key monthly checks required to keep your DG in top condition.

• Inspect the air filters to prevent clogging and ensure proper airflow. Check the vacuum indicator for any clogging.
• Check the exhaust system for blockages, leaks, or excessive carbon buildup.

• Examine the fuel tank for leaks and contamination.
• Inspect hoses, clamps, and connections for signs of wear, cracks, or looseness.
• Examine the fuel filter for leaks.

• Verify coolant levels and top up if necessary.
• Check radiator belts for wear and tear and proper tension.

• Monitor lube oil levels and ensure they meet operational requirements.
• Inspect for any oil leaks that could indicate filter, seal, or gasket issues.

• Check battery terminals for sulphate formation or loose connections.
• Ensure the electrolyte levels are sufficient.
• Check the output of the battery charger.

• Verify control panel operations, including positioning of selector switch, alarms, and fault indicators.
• Ensure synchronization settings are correctly configured if running parallel generators.

• Assess ventilation, insulation, and overall safety conditions.
• Keep the DG area clean and free from obstructions.

Critical Operational Parameters to Monitor:

• Engine RPM
• Oil Pressure
• Coolant/Water Temperature
• AC Voltage Output
• Frequency
• Load Amperage
• Battery Voltage
