A 10 MVA, 6.9 KV. star connected generator has positive, negative and zero sequence reactance of 25, 20 and 7% respectively. An inductive reactor with 6% reactance based on the rating of the generator is placed in the line from neutral to ground. For a line to line fault at the generator terminals when it is operating atrated voltage and is disconnected from the system determine, (a) Initial symmetrical r.m.s. line and neutral currents and (b) line to line and line to neutral voltages.
