What is Fault Analysis and Current Estimation Techniques about?

A three-phase fault occurred at the midpoint between buses 1 and 2. The fault impedance was 0.1 Ω. For a single-line-to-ground fault, the fault current was calculated to be -2.8571 kA. For a line-to-line fault, the fault current was calculated to be -2.8868 kA. A symmetrical fault occurred at bus 4 with a fault impedance of 0.5 pu. The fault current at bus 4 was calculated to be -7102.458 A. The MVA fault level was 135.3 MVA. The current contribution from generator G2 was calculated to be -3197.996 A.
