Unknown network component is designed for cases where the user cannot know the details about the source but have the prospective short circuit current and external impedance value at a location. Once this component is inserted ElectricalOM will disregard source characteristics and use these PFC and Ze values for all calculations downstream to unknown network component.


See picture below for a representation how Unknown Network component works.




This feature (Unknown network) is also available with junction box component. User needs to tick Unknown network point box to enable it. Now the JB will act the same way as the Unknown network component.
