Your equipment shortlist
Compare equipment before you request it.
Review the published facts side by side. Matching a voltage or MVA rating does not establish compatibility. Ask your project engineer to review the complete unit records.

What still needs to be checked?
Confirm frequency, cooling-stage ratings, impedance and its base, taps, vector group, grounding, BIL, site conditions and included scope against the project specification. A table cannot approve the fit.
