11kV Transformer Specification Checklist
Engineering Intent
An 11kV transformer RFQ should define voltage ratio, capacity, transformer type, impedance, vector group and installation environment.
This article is written for engineers, EPC buyers and procurement teams who need to turn 11kV transformer specification into a clear technical request instead of a vague product inquiry.
Key Selection Data
| Item | Data to Confirm |
|---|---|
| Check 1 | 11kV primary system details |
| Check 2 | Secondary voltage and load type |
| Check 3 | Dry type or oil immersed selection |
| Check 4 | Indoor, outdoor or package substation installation |
Standards and Evidence to Request
- IEC 60076 series
- IEC 60076-11 for dry type when applicable
- Project utility requirement
For project approval, request a technical datasheet, outline drawing, wiring or terminal diagram where applicable, routine test report and nameplate information before shipment.
Common Specification Mistakes
- Only writing 11kV transformer without secondary voltage
- No installation environment stated
- No vector group or impedance information
RFQ Checklist
- Confirm 11kV voltage ratio
- State kVA rating
- Select dry type or oil immersed
- Attach transformer schedule
