JDZX Voltage Transformer for 11kV Panels
Engineering Intent
JDZX voltage transformers are used in medium-voltage switchgear for voltage measurement, protection and indication circuits.
This article is written for engineers, EPC buyers and procurement teams who need to turn JDZX voltage transformer into a clear technical request instead of a vague product inquiry.
Key Selection Data
| Item | Data to Confirm |
|---|---|
| Check 1 | 11kV system voltage |
| Check 2 | Voltage ratio |
| Check 3 | Burden and accuracy class |
| Check 4 | Panel installation dimensions |
Standards and Evidence to Request
- IEC 61869
- Switchgear panel drawing
- Routine test report
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
- Model selected without ratio
- No fuse or protection arrangement
- No space check in panel
RFQ Checklist
- State voltage ratio
- Confirm burden and class
- Attach panel drawing
- Request terminal diagram

Current Transformer Ratio Selection Guide
CT ratio should match feeder current, meter or relay input, accuracy requirement and future load margin.
CT Accuracy Class 0.5 vs 5P Explained
Metering CTs and protection CTs use different accuracy classes, so 0.5 and 5P should not be treated as interchangeable.
Current Transformer Burden Calculation
CT burden must include meter or relay load plus secondary cable resistance to maintain accuracy.
