Finding oil on a transformer surface does not always reveal the actual source of the leak.
Oil can travel along adjacent surfaces before dripping, making accurate inspection essential.
Maintenance teams should pay particular attention to:
1. Gaskets and Flanges
Aging, loss of compression, damaged sealing surfaces, or improper joint assembly can compromise the seal.
2. Valves and Pipe Connections
Worn sealing elements, defective joints, or damaged connections may allow insulating oil to escape.
3. Radiator Connections
Flange seals and connecting joints can develop leaks over time or following maintenance work.
4. Bushings and Inspection Covers
Deteriorated seals or defects at mounting interfaces may compromise oil containment.
5. Tank Welds and Surfaces
Corrosion, cracks, or structural defects require careful assessment before selecting a repair method.
Each location presents a different maintenance challenge. The appropriate response depends on the source, severity, equipment design, and condition of the affected component.
Accurate diagnosis is the first step toward effective leakage treatment.
