modelACLine_RL_N
Test model for a three-phase unbalanced inductive-resistive line with neutral cable
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example demonstrates how to use a resistive-inductive line model with neutral cable to connect a source to a load.
The model has two loads load_sc_1 and load_sc_2
representing short circuits R=0.
The current that flows through the load depends on the impedance of the line.
Each load is connected to the source with different configurations, but the equivalent impedance between each load and the source is the same. Since the equivalent impedances are the same, each load draw the same current.
