PartialBasicTransformer | Partial model of three-phase transformer |
Partial model of a three-phase transformer, containing primary and secondary resistances and stray inductances, as well as the iron core.
Circuit layout (vector group) of primary and secondary windings have to be defined.
Default values for transformer's parameters (a realistic example) are:
| turns ratio n | 1 | |
| nominal frequency fNominal | 50 | Hz |
| nominal voltage per phase | 100 | V RMS |
| nominal current per phase | 100 | A RMS |
| nominal apparent power | 30 | kVA |
| primary resistance R1 | 0.005 | Ohm per phase at reference temperature |
| reference temperature T1Ref | 20 | °C |
| temperature coefficient alpha20_1 | 0 | 1/K |
| primary stray inductance L1sigma | 78E-6 | H per phase |
| secondary resistance R2 | 0.005 | Ohm per phase at reference temperature |
| reference temperature T2Ref | 20 | °C |
| temperature coefficient alpha20_2 | 0 | 1/K |
| secondary stray inductance L2sigma | 78E-6 | H per phase |
| operational temperature T1Operational | 20 | °C |
| operational temperature T2Operational | 20 | °C |
| These values give the operational parameters: | ||
| nominal voltage drop | 0.05 | p.u. |
| nominal copper losses | 300 | W |
