Technical values and record basis
Supplied nameplate and maintenance report for one unit in a two-unit offer; match the second unit separately and reconcile the rebuild dates.
| Phases | Three-phase in the supplied report |
|---|---|
| Cooling | OA / FA in the supplied report |
| Temperature rise | 65°C in the supplied report |
| Impedance and base | 7.2% reported; MVA base to confirm |
| Voltage discrepancy | One report states 140.9 kV delta / 34.5 kV wye; the offer calls the pair nominal 138/34.5 kV |
| Repair items | Recorded bottom-valve oil leaks and broken gauge; present repair completion unverified |
| Remanufacture date discrepancy | Reviewed nameplate states March 2008; offer email claims a 2012 rebuild. Confirm the actual work history for each unit. |
| Nameplate impedance and base | 7.26% at 39.6 MVA on the reviewed plate; separate maintenance report rounds to 7.2% |
| Conductor on reviewed plate | Copper |
| Insulation / BIL on reviewed plate | HV 550 kV / LV 200 kV; verify both units |
Details to confirm for this listing
- Both final nameplates and exact voltage fit; rating stages and impedance bases
- Current leak/gauge repairs, oil analysis, full tests, service history and transport scope
Technical highlights
- The offer represents two Westinghouse transformers rebuilt by GE Energy, rated 39.6/52.8/66 MVA. One supplied nameplate states March 2008 remanufacture, conflicting with the email's 2012 rebuild claim; reconcile the rebuild history for each unit.
- The offered nominal 138/34.5 kV description differs from the 140.9 kV delta / 34.5 kV wye nameplate fields in the supplied report for one unit. Resolve this before approving project duty; 138 kV is not presented as a verified nameplate rating.
- The readable report covers one unit, not both. It records three-phase, 60 Hz, 66 MVA, OA/FA cooling, 65 C rise and 7.2% impedance; confirm the nameplate and rating basis for each unit.
- Maintenance entries record bottom-valve oil leaks through March 2026 and a broken gauge in November 2025. Present repair completion and condition have not been verified.
- A July 2025 dielectric result was recorded as unacceptable, followed by later acceptable readings. Obtain the complete history, current inspection and new tests appropriate to the purchase.
- Request the second unit's individual nameplate, test and maintenance package. Historical service entries do not establish present operating status, readiness to energize or availability.
