Hi, Looking at National Grids shapefiles (published online [1] but no licence stated so assumed to be copyright), then it appears that names like the one you linked to are used but on the circuit rather than the line. For example, each line-string (or "way" in OSM terminology) can have a circuit 1 and circuit 2 name, or just a circuit 1 name.
I've attached the first 2 rows of the shapefile here as a CSV if you'd like a look. As you will see they are not referred to as "names" so maybe ref=* is better. In regards to being able to survey on the ground, I do seem to remember seeing signs on pylons but cannot recall exactly what was on it. I would avoid removing any tag data altogether.
