Short Circuit Data: reactor
Typical equipment impedances (%Z) and X/R ratios for short circuit calculations per IEEE 141 (Red Book) and IEEE 551 (Violet Book). Covers transformers by kVA, utility sources by voltage level, cables, motor contributions, generators, and reactors.
| equipment type | rating label | notes | xr ratio max (dimensionless) | xr ratio typical (dimensionless) |
|---|---|---|---|---|
| reactor | CURRENT_LIMITING | Current limiting reactor; very high X/R (low R); pct Z is specified impedance | 80 | 40 |
