Oil-immersed transformers are critical components in power distribution systems, ensuring efficient energy transmission. However, oil leakage is a common issue that can lead to equipment failure, environmental hazards, and increased maintenance costs. Understanding the causes and implementing preventive measures is essential for maintaining optimal performance.

Common Causes of Oil Leakage in Oil-Immersed Transformers

1. Gasket and Seal Degradation – Over time, gaskets and seals deteriorate due to temperature fluctuations, chemical exposure, and mechanical stress.

2. Poor Welding or Manufacturing Defects – Weak joints or substandard welding can develop cracks, allowing oil to escape.

3. Overheating – Excessive heat expands the oil, increasing internal pressure and straining seals.

4. Mechanical Damage – External impacts or vibrations can weaken the transformer tank, leading to leaks.

5. Corrosion – Rust and corrosion on the tank or fittings create weak points where oil can seep out.

Preventive Measures for Oil Leakage

To minimize leakage risks in oil-immersed transformers, follow these best practices:

• Regular Inspections – Check gaskets, seals, and welds periodically for signs of wear.

• Use High-Quality Materials – Opt for corrosion-resistant tanks and durable sealing components.

• Temperature Monitoring – Install cooling systems and temperature sensors to prevent overheating.

• Proper Installation – Ensure correct alignment and torque settings for bolts and gaskets.

• Leak Detection Systems – Implement sensors to alert operators of potential leaks early.
