Ground fault in Non-effectively grounded systems
Direct grounded system
In direct grounded systems, an ground fault on one phase is indicated by voltage
collapse in that phase. The other healthy phase will still have normal phase-to-ground
voltage. The residual sum will have the same value as the remaining phase-to-ground
voltage, which is shown in Figure 207.
