What device measures temperature continuously inside HV motor or generator stator windings?
Direct Answer
Option C: Resistance Temperature Detectors (RTD - PT100) or Thermocouples
Resistance Temperature Detectors (RTDs), typically PT100 sensors, provide continuous, accurate monitoring of stator winding temperatures. This is essential for preventing insulation degradation caused by overheating. These devices are standard in HV machinery, allowing the protection system to trigger alarms or trips before thermal damage occurs, in accordance with IEC 60092 standards.
