✔ Consider liquid-immersed cooling solutions for high-performance transformers.

ETT equips its transformers with efficient cooling systems to minimize the risk of overheating.


6. Oil Contamination

Challenge:

Contaminated or degraded transformer oil affects insulation and cooling efficiency.

Solution:

✔ Conduct routine oil analysis to detect contaminants.
✔ Replace or purify transformer oil through filtration or degassing.
✔ Ensure airtight seals to prevent external contamination.

ETT provides expert guidance on maintaining transformer oil quality, ensuring optimal performance.


7. Shortage of Skilled Personnel

Challenge:

A lack of trained maintenance personnel can lead to improper handling and overlooked issues.

Solution:

✔ Partner with expert suppliers like ETT for professional maintenance support.
✔ Conduct regular training programs for maintenance teams.
✔ Utilize IoT-enabled transformers for real-time monitoring and predictive maintenance.
