Which outcome occurs when a ground fault protection circuit detects leakage current on a three-phase wye distribution system?

💡 Explanation

When ground fault current is sensed, the ground fault protection circuit activates a tripping mechanism because the current differential exceeds a predefined threshold, isolating the faulted phase. Therefore, tripping of affected phase occurs, rather than neutral voltage rise, resonant frequency shift, or phase reversal, which require different fault conditions.
