Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

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 (12)

n_phase

Value: 1

Type: Real

Description: Ratio primary voltage per phase / secondary voltage per phase

C1

Value: "Y"
