Electrical Engineering XYZ MCQs
A thermal protection relay provides protection against what:
- Short circuit
- Overload
- Temperature
- Any of the above
Correct answer: 3. Temperature
Explanation: Thermal protection relays primarily monitor the temperature of components such as motors, transformers, or other electrical equipment. When the temperature rises beyond a certain threshold, indicating potential overheating, the relay triggers a protective action such as shutting down the system or activating an alarm.
