This paper presents a circuit for realising a fuse-programmable capacitor on-chip. The trimming mechanism is implemented using integrated circuit fuses which can be blown in order to lower the resulting equivalent capacitance. However, for integrated circuits, the non-zero fuse resistance for active fuses and finite fuse resistance for blown …
Fuse-less Capacitor Bank: Consists of capacitor strings without fuses, reducing costs and space but needing advanced control systems to handle faults. Fault Management : Fuse-less banks require immediate fault clearing by tripping circuit breakers and sophisticated relay systems to detect and manage faults.
Fusing and Protection The main purpose of the fuse on a capacitor bank is to clear a fault if a capacitor unit or any of the accessories fail. The fuse must clear the fault quickly to prevent any of the equipment from failing violently. Ruptures of capacitors have historically been problematic, so fusing is normally

Top Cause of Single-Phase Motor Malfunctions | Fluke
Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost …
