Power capacitors: fundamentals of power capacitors
Internally fused units consist of elements that are each protected by a series connected fuse inside the capacitor enclosure. As an element fails, the internal fuse protecting that element clears. After the fuse clears, the voltage on elements in parallel with the failed element rises and the voltage on the capacitor unit rises.
