1. Phaseback VSGR stabilizes Voltage Potential between each Phase & Ground, equalizing the Impedance on each phase. See before (Phaseback VSGR OFF) & after (ON) in above charts.
2. Note: Current takes the path of least resistance. Phase B will flashover to Phase A, with Phaseback VSGR OFF.
3. With Phaseback VSGR ON, notice Impedance values have been corrected, which removes the flashover path.
This happens at the speed of Current flow, preventing the flashover & subsequent Arc Flash event!
