Facility where I work is installing electrostatic precipitator. As part of the equipment three transformer/rectifier units will be installed. They will step up and rectify voltage from 480VAC to 83kVDC. Those are oil filled transformer/rectifier units. Are those kind of units covered by Article 450 of NEC and if so do I have to treat them as rated above 35,000V for the purpose of indoor installation? Any other NEC Article that would apply?
