A fault occurring at the terminals of an unloaded AC generator operating at its rated voltage has resulted in the following sequence currents and voltages: Positive sequence current = j3 p.u. Negative sequence current = -j5.5 p.u. Zero sequence current = j2.5 p.u. Positive sequence voltage = 2 p.u. Negative sequence voltage = 2 p.u. Zero sequence voltage = 2 p.u. What is the type of fault?
