In the inspection scenario, what is the diameter of the insulator to be inspected?

Explanation:
The measurement you use to interpret the thermographic image is the insulator’s diameter given in the scenario. This 7-inch diameter sets the scale for the inspection—how large the insulator appears in the image, how many pixels cover it, and how far your camera should be from the target to get a usable, detailed view. With a 7-inch diameter specified, you compare any thermal anomalies against that known size to judge whether a hotspot or defect is significant. The other numbers don’t match what the scenario describes, so they aren’t the correct reference for this inspection.
