http://psspy.org/psse-help-forum/question/8296/can-i-calculate-short-circuit-ratio-scr-using-psse/?answer=8300#post-id-8300The SCR is not calculated, but activity ASCC reports the short circuit power at the bus for three-phase faults. From that you can calculate SCR.Tue, 25 May 2021 00:43:31 -0500http://psspy.org/psse-help-forum/question/8296/can-i-calculate-short-circuit-ratio-scr-using-psse/?answer=8300#post-id-8300Comment by Swej for <p>The SCR is not calculated, but activity ASCC reports the short circuit power at the bus for three-phase faults.
