← TechnologyWhich outcome occurs when excessively sensitive ground fault protection settings are configured in an industrial motor control center?
A)Nuisance tripping of circuit breakers✓
B)Harmonic resonance in power grid
C)Motor bearing currents increase rapidly
D)Transformer core saturation accelerates quickly
💡 Explanation
When excessively sensitive, ground fault protection misinterprets normal leakage as a fault, causing nuisance tripping of circuit breakers; this is due to incorrect differential current monitoring because the threshold is too low; therefore, breakers trip unnecessarily rather than only during actual faults.
