Which transient behavior results when rapidly switching large inductive loads in a power grid sub-station?

💡 Explanation

Ferroresonance generates unstable oscillations because the nonlinear inductance of the transformer interacts with the grid capacitance, rapidly causing voltage instability; therefore ferroresonance represents a significant grid risk, rather than harmonic amplification.
