Two 11 kV, 20 MVA 3-φ star connected generator operate in parallel. The positive negative and zero sequence reactance of each being respectively, j 0.18, j 0.15, j 0.10 pu. The starpoint of one of the generators is isolated and that of the other is earthed through 2 Ω resistor. A single line to ground fault occurs at the terminals of one of the generators. The voltage across grounded resistor is
