What Are the Common Issues with Pad Mounted Transformers

Pad Mounted Transformers are essential for reliable power distribution, but like any critical equipment, they can face operational challenges. At CONSO·CN, we’ve helped hundreds of clients troubleshoot and prevent these issues—here’s what you need to know.

Top 5 Common Pad Mounted Transformer Problems

1. Overheating – Caused by overloading, poor ventilation, or cooling system failure.

2. Oil Leaks – Degraded gaskets or tank corrosion in oil-filled units.

3. Moisture Ingress – Leads to insulation breakdown and internal faults.

4. Bushing Failures – Cracked or contaminated bushings disrupt power flow.

5. Corrosion & Rust – Accelerated by harsh weather or improper sealing.

How CONSO·CN’s Pad Mounted Transformers Minimize These Risks

3 Frequently Asked Questions About Pad Mounted Transformers

Q: What causes a Pad Mounted Transformer to overheat?
A: Overloading, blocked ventilation, failing cooling fans (in dry-type units), or degraded oil (in oil-filled units) are common causes. Regular thermal imaging can detect hotspots early.

Q: How often should Pad Mounted Transformer oil be tested?
A: For oil-filled units, test every 3-5 years. Look for dissolved gases, moisture, and acidity—key indicators of internal problems.

Q: Can corrosion permanently damage a Pad Mounted Transformer?
A: Yes, especially in coastal or industrial areas. Our CONSO·CN models use galvanized steel and anti-corrosion coatings for added protection.
