Equipment overview

Nameplate high side 4,160 V delta; low side 480Y/277 V. Verify selected taps, grounding and application.

Actual supplied nameplate reviewed for this transformer. Nameplate 400/448 kVA at 55/65°C rise; 204 US gallons oil.

Three-phase, 60 Hz, ONAN with aluminum high- and low-voltage windings. Nameplate ratings are not a current test report. Confirm fluid condition, insulation, accessories, taps, grounding, protection, installation and intended direction of operation with a qualified transformer specialist.

The primary and secondary fields preserve the documented application convention. Public high/low labels are ordered by the nominal line-to-line winding voltage; Y/neutral values remain associated with their own winding. Neither a voltage pair nor a search match establishes reversible suitability or site compatibility. Plate images and serials are kept private pending disclosure authorization.
