During the operation of power systems such as power generation, transmission, substation, and distribution, equipment and lines may suffer from thermal defects in various levels because of harsh operating conditions and long-term operation. Infrared thermal imagers provide a non-contact defect testing devices. Due to temperature measurement, image processing, and intelligent diagnosis, operators can test for safety hazards and identify defects at a safe distance, avoid accidents, and ensure stable operation for the power grid.

Main Applications in Power Systems

Wind Farm Monitoring

If wind turbines are not promptly addressed, they may overheat or even collapse. Infrared thermal imagers can provide panoramic scanning in 5 km range, providing high-definition images and real-time thermal condition data of the equipment. For example, it can detect abnormal heating of generator bearings or gearboxes, which will likely fail under high load. This allows for timely detection of potential problems before they escalate into serious failures, such as sudden shutdown of turbines during peak power consumption.

Photovoltaic Panel Inspection

Solar panels are exposed to harsh outdoor environments such as heat stress and storms that may trigger latent defects such as cracks or component damage. Such defects can be readily identified using infrared thermal imagers by detecting temperature differences: a cracked cell would be cooler than the surrounding area because it cannot generate heat during the energy conversion process. By indicating these faulty areas, the maintainer would only replace the spoilt panel as opposed to the whole array, thereby improving work efficiency and saving costs.

Transmission Line and Substation Monitoring

Transmission line insulators will gradually age due to long-term exposure to strong electric fields and pollutants. Thermal imaging cameras can monitor insulators throughout their life cycle and track aging trends. Aging insulators often have uneven heat distribution due to reduced insulation capacity. In substations, the camera provides online temperature monitoring with auto inspection, alarm and data analysis functions. It can continuously scan busbars, circuit breakers and terminals, and provide an alarm if the temperature exceeds the safety level to ensure the stable operation of key equipment.

Cable Trench and Transformer Safety

Cable trenches that carry high-voltage cables are prone to overheating due to loose joints, which can cause fires. Infrared thermal imaging cameras provide real-time temperature measurement and auto-alarm capabilities to prevent such dangers. It is even able to detect heat through cable insulation, showing hidden joint problems before smoke or sparks appear. For transformers, a common culprit in power system breakdown, thermal imaging equipment provides intelligent diagnosis. By comparing the heat distribution patterns of the core and windings, it can accurately detect heating problems such as short circuits, enable timely maintenance, and avoid catastrophic oil leaks or explosions.

Emergency Repair Support

When power is interrupted by extreme weather (such as thunderstorms and blizzards), infrared thermal imaging cameras play an important role in emergency repair. It can quickly locate damaged sections of transmission lines covered by snow or debris by identifying temperature anomalies. There may be no heat flow in the broken line, while abnormal heat will be emitted in the short-circuited area. This allows the repair team to focus on critical areas and reduce the time of power restoration. For example, after a storm, it can distinguish between lines that are just shaking and lines that are internally damaged, avoiding unnecessary replacement.
