modelTwoPortResistance

Model of a resistance with two electrical ports

Extends from Modelica.Electrical.Analog.Interfaces.ConditionalHeatPort, BuildingSystems.Electrical.AC.ThreePhasesUnbalanced.Interfaces.TwoPort.

Information

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

image

The model represents the lumped resistance as shown in the figure above. Assuming that the resistance R is the overall resistance of the cable, each line has a resistance equal to R/3.
