measurements of three-phase voltage and current samples obtained from the PSCAD/EMTDC. Fig. 8 depicts the 220 kV, 50 Hz simulated system one-line diagram. The other related parameters of the simulated system are shown in Table 1, transmission lines are assumed completely transposed. Fig. 9 & 10 show 3ph voltages and currents waveforms for 3ph to ground fault at 50% of the second line without and with UPFC respectively. It is clear that when UPFC is involved in the fault loop, the the voltage and current signals would be deviated from the actual value.
