Not sure why it would be questioned when talking about a distance to a fence, but yes, it applies to outdoor electrical equipment including transformers that are covered by the scope of the NEC.

3 meters for upto 14,000 Volts seems Ok to me.
My first question would be what live parts, since the table is for distance from fence to live parts? does that include inside the transformer enclosure?
It seems to me that the only rational interpretation would be that any part that is ever energized whether the energized part is accessible or not would be covered by this table.
Yes, i would think so

What's the difference between Tables 110.31 and 110.34 in terms of when which table would apply?
Is there any time that only table 110.34 would apply, even inside a fence? Such as all equipment being built with a dead front, that would normally enclose its live parts, and only expose them during maintenance.
Is it because it is a fence specifically, that you need to consider 110.31? For instance, if you surround your equipment with a block wall in place of a fence, would only 110.34 apply?
