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.
| Compare | 120 MVA 138/34.5 kV Georgia Solar GSUJJ-TX-004 | 42 MVA 138/34.5 kV Virginia TransformerJJ-TX-102 |
|---|---|---|
| Manufacturer | Georgia Transformer | Virginia Transformer |
| Rating / output | 72/96/120 MVA; 25.2/33.6/42 MVA tertiary | 25.2/33.6/42 MVA |
| Voltage / winding arrangement | 138/34.5 kV with 12 kV buried-delta tertiary | 138/34.5 kV |
| Vector group | YNyn0+d1 | Winding connections and phase shift to confirm |
| Frequency | 60 Hz | Not documented; confirm with J&J |
| Cooling | ONAN / ONAF1 / ONAF2 | Not documented; confirm with J&J |
| Impedance and base | Measured H–X: 6.93% at 72 MVA; design value 7.2% | Not documented; confirm with J&J |
| Tap changer | HV OLTC; 117.3–158.7 kV (±15%); confirm the final switch and step schedule | Not documented; confirm with J&J |
| Insulation / BIL | HV line 650 kV; HV neutral, LV line and LV neutral 200 kV | Not documented; confirm with J&J |
| Quantity represented | 1 documented unit | 1 schedule entry; individual identity to confirm |
| Technical details / open items | Solar GSU design; ONAN/ONAF1/ONAF2, 60 Hz, three-phase; Vector group YNyn0+d1 with HV OLTC and conservator oil system; Nameplate rating is used; an outline-drawing discrepancy requires final seller confirmation | Ratings and manufacturer are transcribed from the J&J-submitted schedule; verify them against the matching nameplate and current technical package.; Service history, present condition, frequency, winding arrangement, impedance, tap changer and accessories require unit-specific confirmation.; Historical schedule dates do not establish current dispatch timing, manufacture year or transferable warranty. Request present release terms and any applicable warranty in writing. |
| Evidence reviewed | Serial-specific nameplate and approval drawings reviewed | J&J-submitted inventory schedule; matching unit-specific technical records to confirm |
| Technical value basis | Supplied unit nameplate; the nameplate takes precedence over the differing outline-drawing rating. | Submitted inventory schedule; manufacturer and electrical rating are representations, not an individual nameplate match. |
| Details to confirm | Resolve the outline-drawing rating discrepancy and confirm the final drawing revision; Current preservation, complete tests, dimensions and included accessory schedule | Individual identity and quantity, current photos, condition/service history and preservation; Frequency, cooling/rise, winding connections and clock, impedance/base, BIL, conductor/fluid and tap schedule; Factory/current tests, included accessories, dimensions/weights and final release/transport scope |
| Represented condition | Brand new, never used and never energized; approval drawings reviewed | Condition and service history require confirmation |

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.
