Ignoring transmission impedance in network models
Ignoring transmission impedance in network models
(OP)
Why do some utilities simulation tools ignore the transmission impedance in network models for its analysis? I understand that it will increase the voltage drop and it would not allow proper sizing of conductors. But, it is necessary for sizing of breakers at substations and other devices, also for faults at the station buses.

Occasionally a source could be consider as an infinite bus (zero impedance) just for simplification. However modeling network with negligible impedance does not sound right without additional explanation.
