engineering recuitment Indian Coast Guard Yantrik Mock Test 2024 Power Systems Fault Analysis Line To Ground Fault
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. What is the type of fault?
Positive sequence current = j 3 p.u
Negative sequence current = -5.5 p.u
Zero sequence current = j 2.5 p.u
Positive sequence voltage = 2 p.u
Negative sequence voltage = 2 p.u
Zero sequence voltage = 2 p.u
