How do I get the short circuit current with the ASCC_3 API?

I'm trying to get the short circuit currents of a case study. I've applied the ascc_3 api to get the three phase faults in the way down bellow:

ierr, Theveninimpedance = psspy.ascc3(sid=0,all=1,status11=1,scfile=scfilename)

I get the thevenin impedances in the console but I want to export them and the currents to excel as well, how do I do this? I've tried using the asccfile and ascccurrents API's but maybe I did something wrong.

ASCC_CURRENTS should return an array you can parse. Do you have the code you tried to use to implement that?

For the Thevenin Impedance I used the following code: def thevenin_impedance(): ierr, Thevenin_impedance = psspy.ascc_3(sid=0,all=1,status11=1) print Thevenin_impedance vector_thevenin=[] vector_thevenin.append(Thevenin_impedance) return vector_thevenin

And to get the Thevenin impedance i used: Impedance = thevenin_impedance()

For the short circuit current I used the following code: def cc_current(): ierr, current = pssarrays.ascc_currents(sid=0,all=1,flt3ph=1) print current vector_current=[] vector_current.append(current) return vector_current

And to get the the short circuit current i used: Short_circuit = cc_current() but it doesn't appear in the console

If you look in the api documentation, the ascc_currents command does not have an ierr in front of it like most of the other api calls. You're probably looping thru an empty array named "current"
