Which of the following is the basic consideration in the design of insulation ?
Correct answer: D. All of the above
- A. Electrical considerations
- B. Mechanical considerations
- C. Thermal considerations
- D. All of the above
Explanation
Transformer insulation must withstand electrical stress, retain mechanical strength against short-circuit forces, and tolerate thermal ageing and temperature changes. Omitting any one of these considerations can cause insulation failure.
