[Tagging] Proposed feature - Voting - Power transformers classification refinement

[François Lacombe]

Hi Joseph,

It's true it can be better with pictures.
I've added two of them in rationale chapter to better illustrate proposed

Let me know if another point misses an illustration.

Cheers

François
