The role of infrared thermal imager in power detection

Infrared thermal imagers generate thermal images by capturing infrared radiation on the surface of objects, which can quickly detect abnormal hot spots in electrical equipment and is an important tool for preventive maintenance.
Core functions
1. Non contact temperature measurement:
Temperature distribution of live equipment (such as cable joints and switch contacts) can be detected without power outage, ensuring safety and efficiency.
Can identify temperature differences and accurately locate potential overheating hazards.
2. Defect diagnosis:
Poor contact: The temperature at the connection point is significantly higher than the surrounding temperature, indicating issues such as looseness or oxidation.
Uneven load: An abnormal temperature in one phase of a three-phase device may be due to overload or phase imbalance.
Insulation degradation: Local overheating of cables may result in increased dielectric loss due to internal insulation damage.
