Power technologyCompare like-for-like reference data
The comparison below uses the common 100, 500, 1,000 and 2,500 kVA capacities from the existing S11/S13/S20 and S22 reference tables. It preserves the original numerical strings, kW units and 75°C load-loss reference. These are selected 10 / 0.4 kV configurations, not a guarantee for every voltage or design.
| Rated capacity (kVA) | Series | No-load loss (kW) | Load loss (kW) | Load-loss reference (°C) |
|---|---|---|---|---|
| 100 | S11 | 0.20 | 1.58/1.50 | 75 |
| 100 | S13 | 0.15 | 1.58/1.50 | 75 |
| 100 | S20 | 0.135 | 1.265/1.20 | 75 |
| 100 | S22 | 0.12 | 1.14/1.08 | 75 |
| 500 | S11 | 0.68 | 5.41/5.15 | 75 |
| 500 | S13 | 0.48 | 5.41/5.15 | 75 |
| 500 | S20 | 0.43 | 4.33/4.12 | 75 |
| 500 | S22 | 0.385 | 3.90/3.71 | 75 |

At capacities up to 500 kVA, paired load-loss values a/b mean Dyn11 first and Yyn0 second. They are two connection-specific values, not a minimum–maximum range.
Read no-load and load losses separately
No-load loss and rated load loss describe different operating effects. Compare the same capacity, voltage ratio, frequency, connection and reference temperature. A lower value in one row does not replace the complete efficiency, impedance, thermal and installation requirements of the project.
Relate the comparison to the actual load
Operating-energy comparisons require the energised hours, load profile, applicable loss conditions and energy cost assumptions. Request the required guaranteed losses for the selected design. Do not apply these 10 kV reference losses directly to 11, 13.8, 15, 22 or 33 kV configurations.
Final ratings, configuration, performance and supply scope are defined in the project technical agreement.
