The former occurs at higher voltage, so it is also referred to as high-voltage self-healing; because the latter also occurs at very low voltage, it is often referred to as low-voltage self-healing.

6 Frequently Asked Questions about “Seychelles self-healing capacitor”
What is self healing metallized capacitor?
Self- healing is the ability of a metallized capacitor to clear a fault area where a momentary short occurs due to dielectric breakdown under voltage. The conditions that lead to a fault vary. In the production of the dielectric film, contamination can occur or a process control problem can result in compromised dielectric strength.
How does deposition thickness affect the self-healing characteristics of a capacitor?
The deposition thickness of the metallized electrode directly influences the self-healing characteristics of the capacitor. Clearing energies of 0.050-0.150 joules are typically considered the proper range for clean clearings.
Which dielectric has a low potential for self-healing?
PPS is an example of a dielectric which does not have high surface oxygen content and therefore has a very low potential for self-healing. The deposition thickness of the metallized electrode directly influences the self-healing characteristics of the capacitor.
What is self-healing?
Self-healing is the spontaneous extinction of a local electrical arc due to the destruction of the electrodes during the process. It occurs in capacitors made of metallized films of plastics with a thin layer of metal (the layer thickness e is ∼10 nm). This phenomenon was first studied by Heywang and Kammermaier, . They showed that
Can a metallized capacitor clear a fault?
The ability of the metallized capacitor to clear a fault is influenced by several factors. The type of dielectric influences the ability to clear. Dielectrics such as polycarbonate and polypropylene have high surface oxygen contents. This is an important factor since oxygen is necessary to vaporize or “burn-off” the electrode around the fault area.
Why does a metallized polypropylene capacitor have a partial discharge?
Capacitors made of metallized polypropylene films suffer partial discharges, called self-healing, due to weak electrical defects. Those defects are destroyed by an electrical arc that extinguishes when enough metal of the electrodes is vapourized around this point.
