Repeat Problem 9.43 for a bolted single line-to-ground fault at bus 1.

Problem 9.43

The zero-, positive-, and negative-sequence bus impedance matrices for a two-bus three-phase power system are

Determine the per-unit fault current and per-unit voltage at bus 2 for a bolted three-phase fault at bus 1 . The prefault voltage is 1.03 per unit.
