Information

This example demonstrates how to use a line model to connect a source to a load that uses medium voltage commercial cable information.

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 impedance of the line.

The remaining three loads R1, R2, and R3 are resistive loads. Each load is connected to the source with different configurations, however 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.
