modelACLine_L_N
Test model for a three-phase unbalanced inductive line with neutral cable
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example demonstrates how to use a purely inductive line model with neutral cable to connect a source to a load.
The model has four different loads. The load sc_load represents
a short circuit R=0. The current that flows through the load depends
on the resistance of the line.
The remaining three loads L1, L2, and L3
are inductive loads. 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 draws the same current.
