A capacitor is a passive electronic device that stores electric charge. Ceramic capacitors consist of two or more alternating layers of ceramic material as the dielectric and metal layers acting as the non-polarized electrodes. Applications include automotive, bypass, decoupling, filtering, RF, and ESD protection.

I am thinking a multi-staged diode-based voltage multiplier (driven by a square wave/oscillator) that could charge a (large) capacitor. Use something like a JFET to dump the capacitor through the primary side of a step-up transformer - somewhat gradually, with a sharp cut-off to collapse the secondary to high voltage on the kick-back.

Internal faults are caused by failures of capacitor elements composing the capacitor units, and units composing the capacitor bank. Other faults inside the bank can be a flashover within the rack (short circuit over a single or multiple series groups of units of the same phase) and rack phase-to-phase and phase-to-earth faults.
