Buyer takeaway: Use the nameplate to identify the unit and frame the technical review. Keep a legible original image alongside any transcribed specifications.
Read ratings in their original context
Capture the complete voltage and rating schedule, not only its largest MVA number. Record each cooling stage, temperature-rise basis, frequency and phase information shown. Keep units explicit, especially when low-side values are in volts rather than kilovolts.
Keep winding information intact
Transcribe connections, tap positions, impedance and the referenced rating base. A slash in a catalog description can represent cooling ratings, selectable voltages or other arrangements. Use the winding diagram to resolve the meaning rather than inventing a tertiary or vector group.
Match the plate to the actual asset
Check manufacturer and serial number against photographs, drawings and test reports. Record original manufacture and subsequent rebuild information separately. Note unclear digits for confirmation instead of publishing a confident interpretation of an unreadable photograph.
| Review area | Buyer action |
|---|---|
| Identity | OEM, serial number, original year and documented rebuild history |
| Electrical | Full MVA/kVA, winding voltages, connections, taps and impedance base |
| Handling | Check whether stated weights describe operating or shipping configuration |
Can the nameplate replace the outline drawing?
No. The plate summarizes ratings and identity. The correct outline drawing provides dimensions, terminals, clearances and handling details needed for site and transport planning.
Move from review to equipment selection
Send your specification or equipment ID, project location and required date. We’ll identify the information available for the proposed unit and the items that still need confirmation.
This guide supports procurement. Final design, suitability, testing and acceptance remain with the project’s qualified professionals and agreed documents.
