5.2.1.1. Case 1: Single Phase Voltage Sag<br />
The great number of faults is single-phase line to ground fault (SLGF). In this<br />
case, single phase to ground fault is analyzed. This fault occurs on Phase-C. The<br />
phase voltage decreases to 70% from its nominal value during the period of 0.3-0.4 s.<br />
In this fault, phase jump occurs between source-side and load-side voltages.<br />
Phase jump is compensated by using presag compensation method.<br />
