Returning Angles and Impedances after calling SCMU

Hello!

Does it exist an easier way of returning angles for fault currents and impedances after calling SCMU?

As of now I'm retrieving angles and impedances doing calculations on Short circuit currents and bus voltages retrieved by using the SCBUS and SCBRN2 commandos, i.e.: degree( phase( returned current of SCBRN2 commando ) ) for getting the Angle and SCBUS(fromBus, 'VA') / SCBRN(fromBus, toBus, 'IA' ) for getting the impedance.

Is there another way of doing it? like a SCIMPEDANCE or SCANGLE retrieval commando?

I'm running into problem with getting values for the impedance that concur with the one PSSE presents after doing SCMU/SCOP graphically because sometimes it means me dividing 0 V / the retrieved 'IA'-SCBRN2-current when trying to get ZA because the fault is in phase A ( = 0 V)

Kind Regards
