## Buildings.Electrical.AC.ThreePhasesUnbalanced.Interfaces.Examples.WyeToDelta

Test for Y to D connection

### Information

This simple example shows how to use a Y to D adapter.

The probe `probe_Y` mesaures the phase voltages before they are converted into D. Their RMS value is equal to 480/sqrt(3) V.

The probe `probe_D` measures the phase voltages after the conversion to D. Their RMS value is equal to 480 V, the line voltage provided by the voltage source.
