What is the Thermography Hotspot Temp & How does it work?

Thermography is a non‑contact method that captures infrared radiation emitted by electrical components, allowing engineers to estimate the surface temperature of a hotspot without disrupting operation.

The temperature rise of a hotspot above ambient is calculated by subtracting the ambient temperature from the measured hotspot temperature, providing a Ξ”T that is directly related to the risk of insulation failure.

\Delta T = T_{\text{hot}} – T_{\text{amb}}
Ξ”T = temperature rise above ambient (Β°C)

Risk classes are assigned based on the relationship between Ξ”T, the equipment’s rated temperature, and industry guidelines; higher Ξ”T or temperatures approaching the rating indicate a higher probability of failure and thus a higher risk class.
