Hi all

I am having a small problem with calcualtion of system transfer reactance when a fault occurs.



Figure 1



Figure 2

Figure 1 has shown the system before the fault and Figure 2 has shown the systemduring the fault.

I presume star/delta transformation is the key, am I correct?

The solution is 3(Xs + Xt) + XL.


Thanks very much
