User was conducting a DC AF analysis with IEC DC SC option selected and only had DC Solar PV components as a source in the system. But was getting 0kA for DC Bolted/Arcing Fault and 0cal/cm2 incident energy for all his buses.



The reason is that DC IEC short-circuit should not have generators in the network. But DC Solar PV component is modeled as a generator in PTW, so it is ignored in the DC IEC SC study and hence the user was getting zero bolted fault current for all the buses.
