Question:
As shown in Figure 9.21 (a), two three-phase buses \(a b c\) and \(a^{\prime} b^{\prime} c^{\prime}\) are interconnected by short circuits between phases \(b\) and \(b^{\prime}\) and between \(c\) and \(c^{\prime}\), with an open circuit between phases \(a\) and \(a^{\prime}\). The fault conditions in the phase domain are \(I_{a}=I_{a^{\prime}}=0\) and \(V_{b b^{\prime}}=V_{c c^{\prime}}=0\). Determine the fault conditions in the sequence domain and verify the interconnection of the sequence networks as shown in Figure 9.15 for this oneconductor-open fault.
