Equipment checklist
Pad-mount, dry-type, cast-coil, liquid-filled, unit-substation, and station-class units. Keep labels, schedules, accessories, and visible condition tied to the exact Columbus, OH lot.
Columbus, OH / 75 kVA–50 MVA
A Columbus evaluation can cover one asset or a coordinated lot. Document the transformers, the release schedule, condition, quantity, and path to grade so the equipment and project scope can be reviewed together.

Columbus identification file
Nameplate photos, kVA/MVA, primary and secondary voltage, fluid type, test history, and access are most useful. If the Columbus lot is part of a service-entrance modernization, document voltage class, main ratings, transition sections, metering compartments, and utility handoff boundaries. For Ohio records, preserve lineup section order, outage documentation, and the relationship between process loads and the retired distribution equipment.
