Hi. I want to simulate a network and i faced some problems. in my network a three phase to ground fault should appear on the system between time 1.5 and 2.5 s and i want to limit the fault current by entering a capacitor in parallel with an inductor into the grid.(these two are not set to resonance in the power frequency !! they are merely used to form an impedance). but after the entrance of them into the grid, the current in phases a,b,c undergoes a shift upward or downward !! Why this phenomenon happens? I attached phases a and b and c currents. as you can see only phase c current is not shifted and phases a and b currents are shifted.
