Which is NOT a component of a pole inspection?

A winding test is typically associated with electrical equipment, specifically to assess the insulation and integrity of the winding coils within transformers or motors. In the context of pole inspections, which generally focus on the structural integrity and condition of utility or telecommunication poles, the components of an inspection would include visual inspection to check for any obvious signs of damage or wear, a sound test which involves tapping the pole to listen for hollow sounds that indicate internal decay, and a rocking test to evaluate the pole's stability and whether it can withstand external forces.

The inclusion of visual, sound, and rocking tests aligns closely with the physical structural assessment of poles, while the winding test pertains to an entirely different area of inspection relating to electrical components. Thus, it is not a relevant component in the context of pole inspections, making it the correct choice.
