Information

Resistive-inductive model that connects two AC three-phase unbalanced interfaces with neutral line. This model can be used to represent a cable in a three-phase unbalanced AC system.

The model represents the lumped impedances as shown in the figure above. Assuming that the overall cable has a resistance R and an inductance L, each line has an inductance equal to L/3 and a resistance equal to R/3.

The resistance and the inductance of the neutral cable are defined separately using the parameters Rn and Ln.
