A _________ is used to measure the stator % winding temperature of the generator?
Correct answer: C. resistance thermometer
- A. thermocouple
- B. pyrometer
- C. resistance thermometer
- D. thermometer
Explanation
A resistance thermometer, commonly an RTD, measures winding temperature through the change in resistance of its sensing element. Thermocouples can also measure temperature, but RTDs are commonly used for continuous generator stator-winding monitoring.
