Frequently Asked Questions

What is an electrical thermal imaging survey record?

An electrical thermal imaging survey record documents infrared thermography findings on electrical equipment — identifying hotspots that indicate loose connections, overloaded circuits, or failing components. It follows NFPA 70B (electrical equipment maintenance) and IEC 62446 for systematic documentation.

What should a thermal imaging record include?

Key fields include equipment reference, load at time of survey, ambient temperature, emissivity setting, reference and hotspot temperatures, temperature rise ΔT, severity classification, three-phase temperature comparison (to identify imbalance), thermal image reference number, recommended action, and priority.

How are thermal imaging severity levels classified?

Common classification: Attention (ΔT 1–10°C) — monitor at next survey. Intermediate (ΔT 10–25°C) — schedule repair within 1–3 months. Serious (ΔT 25–40°C) — repair within 1–2 weeks. Critical (ΔT >40°C or >70°C absolute) — immediate action required, risk of failure or fire.
