All About Thermal Scanning
What Is It?
Thermal scanning is a non-invasive diagnostic technique that allows us to visualise and quantify changes in the surface temperature of electrical switchgear. An infrared camera converts infrared radiation (heat) emitted from the surface of electrical equipment into electrical impulses. These impulses are mapped as colours which represent the various temperatures. Thermal imaging identifies equipment flaws and pinpoints any hot spots often invisible to the naked eye.
When parts of your electrical systems begin to have problems, they give off heat - usually a sign of electrical resistance or excessive friction. Abnormal temperatures can be easily identified and published.
