functionD_Y

Calculation of hybrid impedance matrices for a delta-wye-connected three-phase transformer.

Extends from Modelica.Icons.Function (Icon for functions).

Information

This function calculates impedance matrices of a hybrid positive-sequece/three-phase transformer modeled as a pi-equivalent.

The transformer that uses this function should have its primary windings connected in delta and its secondary windings connected in wye (star). In addition, this function considers that positive-, negative-, and zero-sequence Norton equivalent impedances have infinite values.
