The most effective method for monitoring abnormal temperature rises in high-voltage cables and busbar joints is to use the FSTS Adhesive Surface Temperature Sensor. By attaching directly to the target surface, it effectively resolves the limitations of traditional infrared thermography, such as susceptibility to environmental reflections and the inability to provide continuous monitoring.
