Err what is this?
https://wiki.openstreetmap.org/wiki/Key:voltage
https://wiki.openstreetmap.org/wiki/Key:frequency

Ratherly agreed defaults don't prevent anyone to specify values in all
situations if ou she/he wants to.

Here is the Zurich Airport ground energy systems documentation.
Three types of supplies : Aircraft, ground and GPU
https://www.zurich-airport.com/~/media/flughafenzh/dokumente/das_unternehmen/laerm_politik_und_umwelt/luft/2018_zrh_aircraft-ground-energy-system_20180214.pdf

OSM would only describe ground power supplies and obviously not mobile GPU
precisely because they move.
It's not so desirable to add power_supply=GPU on the airport perimeter or
relation because you'll have to deald with electronic appliances charging
supplies, industrial supplies or any other numerous kind of supplies in
such a complex facility.

All the best
