Thermal camera for electrical inspection

Short answer

Loose connections, overloads and imbalance can create abnormal heat, but reflections, emissivity and load can mislead. Thermal imaging is a screening and documentation tool, not proof of the electrical cause.

A practical workflow

1. Only inspect equipment you are trained and authorized to approach.
2. Compare like-for-like loaded components and phases.
3. Record load, ambient conditions and the comparison point.

Common mistakes

• Inspecting unloaded equipment
• Measuring shiny bare metal literally
• Removing covers without the required qualification and PPE

Choosing a camera for this job

Start with native IR resolution, thermal sensitivity, field of view and focus. Close electronics work often needs macro or manual focus; broad building scans benefit from a useful field of view and enough native pixels to resolve an anomaly from a safe distance. Compatibility and reporting workflow matter as much as the headline detector specification.
