Which risk increases when rapidly switching between taps on a power transformer?

💡 Explanation

Core saturation increases because the volt-second product during the tap change causes temporary imbalance, driving the core into saturation; therefore saturation, rather than standard losses, is elevated due to this transient rather than steady-state effects.
