Information

RLC line model (T-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, an inductance L, and a capacitance C, each line has an inductance equal to L/3, a resistance equal to R/3 and a capacity equal to C/3.

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