modelFaultedBus
Busbar model with shunt fault
Extends from ObjectStab.Base.OnePinCenter (Shell model for models with one connector in the center of the model).
Information
The shunt fault is modelled as an impedance connected to ground through a breaker. The fault is applied at simulation time FaultTime and stays active for the duration of FaultDuration. For numerical reasons, the fault impedance must not be exactly equal to zero.
