Answer Posted / pradeep vashist
Lightning arrestors limit the crest value of an impulse
voltage. When the voltage reaches a pre-determined value it
provides a discharge path to ground. It provides
a "Spillover Effect" while the Surge Capacitors reduce the
slope of the surge (rate of voltage rise) by momentarily
absorbing initial energy, then releasing it; providing
a "Dampening Effect
