Which 345/34.5 kV transformer is available through J&J?
The current listing is a Georgia Transformer 108/144/180 MVA unit with a 12 kV buried-delta tertiary. Approval drawings and a September 2024 factory acceptance test report have been reviewed.
The reviewed records show 60 Hz, three-phase service, ONAN/ONAF1/ONAF2 cooling, and measured H-X impedance of 6.99% on a 108 MVA base. Your engineering team must confirm the complete package against the project requirements.
What controls 345 kV collector-transformer fit?
Confirm collector voltage and grounding, winding vector, tertiary function, MVA and cooling stages, impedance and tolerance, BIL, LTC/DETC scope, renewable or converter harmonics, reactive requirements, fault cases, protection, losses, sound, accessories, and site interfaces.
- Use final drawings and test values, not a headline ratio, to compare candidates.
- Review switching and temporary overvoltage cases with the responsible system engineer.
- Coordinate transport configuration, oil shipment, bushing/cooler handling, route survey, foundation loads, field assembly, testing, and commissioning.
How should a 345 kV project request the technical package?
Identify the exact opportunity reference or send the one-line, MVA stages, 345 kV system basis, 34.5 kV collector requirements, tertiary duty, study impedance, vector, taps, site, destination, condition acceptance, and schedule.
Public listings are represented opportunities, not reserved or guaranteed stock. Seller authority, serial identity, present condition, exact location, availability, price, included scope, and delivery require current written confirmation and remain subject to prior sale.
Common questions
Written quotes and supporting records control unit-specific ratings, availability, condition, price, and delivery.
Do you have a 345/34.5 kV transformer?
Yes. J&J lists one Georgia Transformer 108/144/180 MVA unit. Call 346-276-9540 for specifications, price, and current availability. Written reconfirmation is required.
Can this transformer serve a collector or substation project?
The Georgia unit’s final project duty and fit must be confirmed from the complete package, one-line, and engineering studies.
Are FAT records available?
A September 2024 FAT report was reviewed for GA447A. Request the current seller package and any disclosure terms for serial-specific records.
Can J&J source another 345 kV transformer?
Yes. Submit the exact ratio, MVA stages, duty, BIL, impedance, vector, taps, tertiary, condition acceptance, site, records, quantity, and needed-on-site date.
Does matching 345/34.5 kV establish compatibility?
No. Ratings, winding connections, tertiary duty, impedance, tap arrangements, condition, and physical interfaces also require engineering review.
Who approves a 345/34.5 kV transformer?
The project team and its responsible engineer must approve system studies, technical suitability, protection, transport, installation, testing, and operation. J&J is not the engineer of record.
