Real world infrared inspection report of electrical panel bus bar. Scan was performed with the IR-555 infrared camera. B phase bus bar shows excessive heating. Some heat energy radiates through wire but not the full length.
Thermal pattern is consistent with a loose or dirty connection.
Clean and tighten connection and re-test. 78 busbar offers a different perspective. Color thermal infrared imaging can produce a vibrant image that can make diagnosis easier. This image shows the value of Iso-Therm display. Iso-Therm is a standard grayscale thermal image that lets you display areas with similar heat energy in a different color.
