In case of single line to ground fault
WebApr 18, 2016 · What is the only case that makes the single line-to-ground fault bigger than the 3-phase short circuit fault? The L-G fault current will exceed the 3Ø fault current whenever you are near the terminal of a D-Y transformer. The Delta winding effectively blocks the zero sequence impedance contributed by the source. Webvoltage profile prior to the ground fault condition. The system will remain in this position until the fault is cleared, or another phase breaks down to form a double line-to-ground fault. Because there is no direct ground path back to the neutral point . of the source in . Figure 3b, the current must return through the
