recordTransformerData
Common parameters for transformers
Extends from Modelica.Icons.Record (Icon for records).
Information
Basic parameters of transformers are predefined with default values.
Note: ratio n is defined between primary / secondary line-to-line voltage; therefore the user has to take into account primary and secondary connection!
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Real | n_phase | 1 | Ratio primary voltage per phase / secondary voltage per phase |
| String | C1 | "Y" | Choose primary connection |
| String | C2 | "y" | Choose secondary connection |
| Real | n | n_phase*(if C1 == "D" and (C2 == "y" or C2 == "z") then 1/sqrt(3) else if C1 == "Y" and C2 == "d" then sqrt(3) else 1) | Ratio primary voltage (line-to-line) / secondary voltage (line-to-line) |
