Gas is usually not liberated due to dissociation of transformer oil unless the oil temperature exceeds?
Correct answer: D. 150°C
- A. 50°C
- B. 80°C
- C. 100°C
- D. 150°C
Explanation
Transformer oil generally begins significant thermal dissociation and gas formation only at temperatures above about 150°C. Normal operating temperatures below this level do not usually liberate gas by oil decomposition.
