Which outcome occurs when asymmetrical saturation affects differential transformer protection?

💡 Explanation

Nuisance tripping happens because asymmetrical saturation generates harmonics that interfere with the differential current measurement, which, in balanced conditions, should ideally be zero; harmonic filters may not fully compensate therefore circuit breakers falsely trigger, rather than staying secure.
