Help please -- what do these ratings mean on a transformer?

[ianeaton230572]

Could anyone explain what the following ratings mean on a transformer?
120kw load, 1000v/500v, 60Hz

Welcome to PF!

maximum load is 120kw, input voltage is 1000v steps down to output voltage 500v AC at 60Hz

120 kW can't be labeled rating of a transformer. 120 kVA can.

Yeah, I saw that too when I researched it and thought maybe its an old way to rate transformers or some wattage that you shouldn't exceed when you place a load on it.
