Does Schneider Electric build transformers per impedance requirements?
Issue:
Impedance being part of the requirements
Product Line:
Transformers
Environment:
Special/custom Build Products
Resolution:
Impedance is not a target attribute for our designs, like efficiency and low heat contribution are. The impedance is the result of a design, not the end goal. But it will be within the proper range based on the Nema Standards below:

| Nema Standards for Transformer Impedance | |
| Transformer Capacity | % Impedance |
| 15 to 150 kVA | 1.5 to 6.0 |
| 225 to 300 kVA | 3.0 to 7.0 |
| 500 kVA | 4.5 to 8.0 |
| 750 kVA | 5.0 to 8.0 |
| *margin of error is +/-7.5% | |
