    Look for transformation from nominal 480V to nominal 600V.

    575V is a 'Canadian' utilization voltage, finding it on a motor nameplate is similar to finding 460V on a US motor.
    Just because you can, doesn't mean you should.

    it is rated at 575 / 10 kw
    P = v^2 / R
    take the ratios and R cancels (it is a constant)
    It is rated 575 / 10 kW.

    Bring it to me and most 480 volt nominal applications I am around typically run at an actual voltage of 495 to 500, but as Jim mentioned most motors connected to it will say 460 on their nameplate. A heater like OP has probably will say 480 volts on it's nameplate if intended to run on 480 volt nominal.

    See this all the time

    Sell it as is! Do not try to get it working, $1000-1500 for transformer. If you try to convert it you will lose 1/3 output as said, plus you need a motor and control transformer and ANYTHING that is not know now.

    You see this all the time with someone who got a GREAT deal on something with the wrong voltage, wrong phase or frequancy.
    A cowboy may get thrown , but they always get up and walk forward.

    On this item yes, get rid of it is likely best option. Had a customer one time purchased a big dry ingredient mixer - food production grade, mostly all stainless, 25 HP drive motor, but the motor was 575 volt motor. It was a NEMA standard frame motor and was well worth buying a new 230/480 volt motor for it. I think the old motor eventually was sold with other scrap metal.
