bus-3001 to bus-3003 unbalanced fault in official file 'savnw' cannot be added successfully.
what my operation process is:
1)open savnw.sav
2)click "Power Flow -> Solve", check in "Convert Generators" and "Convert/Reconstruct Loads"
3) click "Power Flow -> Covert Loads and Generator"
4)click "Power Flow -> Solution -> TYSL", check in "FACT"
5)open savnw.dyr
6)click "Dynamic -> Simulation -> Perform Simulation(STRT/RUN)"
7)create out file, click "Initiate", set 1s and run
8)Adding fault

When I add branch unbalance falut to other bus pair, it can be work;
but Bus-3001 to Bus3003, something wrong, the information in output bar like this:
Channel output file is "C:\Users\Yang\Documents\PTI\PSSE34\EXAMPLE\tt001.outx"

Why official EXAMPLE not work, how to adding unbalance branch fault correctly?
