When a capacitor switch opens, the voltage across the contacts combines system and capacitor bank voltages. This can cause re-strikes, generating overvoltages approaching up to 3 p.u. Re-strikes can trigger issues like ruptured capacitor cans, blown fuses, and contact wear, leading to dielectric failures.
