This information is part of the Modelica Standard Library maintained by the Modelica Association.
Test example with polyphase components:
Star-connected voltage source feeds via a Y-Y-transformer with internal impedance (RT, LT) a load resistor RT.
Using f=5 Hz LT=3mH defines nominal voltage drop of approximately 10 %.
Simulate for 1 second (2 periods) and compare voltages and currents of source, transformer and load.
