Frequent Generator Overheating Outages Linked to Cooling System Faults
"Kavaken detected recurring overheating-related outages in a generator and traced the issue to cooling system faults. Routine actions like coolant refilling, radiator cleaning, and fan replacement restored stable operation."
The Impact
The Issue
Abnormal temperature trends were detected in the generator, causing repeated turbine stoppages. The issue was likely linked to cooling and lubrication system malfunctions, such as reduced coolant level or restricted air circulation.
The Action
Kavaken identified a pattern of overheating-related stops and recommended inspecting the cooling system. The maintenance team refilled the coolant, cleaned the radiator, and replaced the generator slip ring fan. These measures normalized temperature readings and prevented further unplanned outages.
