Abstract：The insulation overheating monitoring device for synchronous compensators can provide early warnings of insulation faults before they occur to ensure the normal operation of the unit. Therefore, the stability and reliability of its operation are very important. Through an in-depth analysis of the typical faults of the insulation overheating monitoring device, it is proposed to employ gas chromatography-mass spectrometry technology for the precise analysis of substances released due to insulation overheating in the condenser's main unit. Based on these analytical results, a systematic methodology can be developed to accurately determine the location and severity of overheating. Furthermore, a comprehensive detection system for the insulation overheating monitoring device can be designed to evaluate whether the performance parameters of the device remain within normal operational limits, thus enhancing the accuracy and reliability of insulation overheating monitoring for the synchronous compensator's main unit, and ensuring the safe and stable operation of the equipment.
