modelImpedance
Model of a three-phase unbalanced impedance without neutral cable
Extends from BaseClasses.Impedance (Partial model of a three-phase unbalanced impedance without neutral cable).
Information
This model represents a three-phase unbalanced impedance without neutral cable. The model extends from Buildings.Electrical.AC.ThreePhasesUnbalanced.Loads.BaseClasses.Impedance and uses the load model from the package Buildings.Electrical.AC.OnePhase.Loads.Impedance. The model computes the voltages, currents and powers on each phase.
