Which risk increases when rapidly switching a capacitor in high-voltage DC transmission?

💡 Explanation

Rapid switching induces large voltage transients because polarization within the dielectric material cannot respond instantly, stimulating intensified partial discharge, and therefore dielectric breakdown accelerates, rather than changes in capacitance value, which varies primarily with temperature.
