What is a common application for infrared thermography in maintenance?

Infrared thermography is commonly employed in maintenance for detecting hot spots in electrical systems. This technique utilizes thermal imaging cameras to visualize the heat emitted by objects, allowing maintenance professionals to identify areas that are operating at abnormal temperatures. Hot spots can indicate potential failures or inefficient components within electrical systems, such as overloaded circuits, failing connections, or malfunctioning equipment.

By identifying these hot spots early, maintenance personnel can take corrective actions to prevent further damage or outages, ensuring the reliability and efficiency of the electrical system. The ability to conduct non-invasive and efficient assessments makes infrared thermography a valuable tool in proactive maintenance strategies, often helping to avoid costly repairs and downtime.

The other options, while relevant to maintenance, do not align with the primary application of infrared thermography. Identifying fluid leaks typically requires other detection methods, measuring electrical insulation resistance is performed through dielectric testing techniques rather than thermal imaging, and evaluating the condition of lubricants involves chemical analysis and does not utilize thermal imaging technology.
