Q: What is the difference between dry-type and oil-filled transformers? A: Dry-type transformers use air or gas as the cooling medium, while oil-filled transformers use oil.
Unlike oil transformers, dry-type transformers have higher thermal stress. IEC 60726 defines maximum average temperature rises for windings:
