Its positive, negative and zero sequenceimpedances are j5.0, j3.0 and j2.2 ohms/phase respectively. A resistive fault occursbetween a single line and earth at the alternator terminals on phase 'a'. The resistanceRr of the fault is 0.502. Show that the fault resistance can be represented by a resistor ofvalue 3Rf in series with the zero sequence impedances and calculate the(i)fault current and(ii)voltage of phase 'b'-earth at the fault point.[10 marks]
