I can see that there are wires connected to the primaries.
Where do they go?
I see six cans there. My guess is that the step up 480V to HV and back down to 575V.

With today's power-hungry In-Car audio equipment, this could become a regular sight in
the years to come.
The wires connected to the primary go to a test stand with volt and amp meters, phase meter, power monitoring system and emergency disconnect switches.
