The external fuse will operate when a capacitor unit becomes short-circuited, isolating the faulted unit. The unbalance protection should coordinate with the individual capacitor unit fuses so
In external fuses it is normally necessary to take the bank out of operation even if one fuse has been operating and change the unit and the fuse. This increases the servicing costs and also
Externally fused type of capacitor bank design is the oldest technology. Each capacitor has an external fuse of either the exposed expulsion type or a sealed current limiting type fuse. Internally fused type of capacitor

This document outlines specifications for 11,000 volt capacitor bank and control equipment. It describes the components, ratings, and requirements for the capacitor banks, which include
When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse. The failed capacitor and fuse must be able to
voltages and currents than fuseless or internally fused banks because an external fuse blowing causes the loss of an entire unit. As a point of reference, fuseless capacitor banks have a unit
Whenever the individual unit of capacitor bank is protected by fuse, it is necessary to provide discharge resistance in each of the units. While each capacitor unit generally has fuse protection, if a unit fails and its fuse blows, the voltage stress on other units in the same series row increases.
Capacitor Bank Protection Definition: Protecting capacitor banks involves preventing internal and external faults to maintain functionality and safety. Types of Protection: There are three main protection types: Element Fuse, Unit Fuse, and Bank Protection, each serving different purposes.
However, if multiple elements fail, the entire bank needs to be replaced as individual unit replacement is not possible. Externally Fused Capacitor Banks: In externally fused banks, each capacitor unit has an external fuse unit. If a fault occurs in a capacitor unit, the fuse unit associated with it will be damaged, isolating the faulty unit.
Externally fused bank technology is the oldest protection strategy for capacitor banks. As the name implies, each unfused (fuseless) capacitor unit is protected with a fuse external to the capacitor (typical construction is illustrated in Figure 8). Externally fused banks use current-limiting or expulsion-type fuses.
Stress specific to the protection of capacitor banks by fuses, which is addressed in IEC 60549, can be divided into two types: Stress during bank energization (the inrush current, which is very high, can cause the fuses to age or blow) and Stress during operation (the presence of harmonics may lead to excessive temperature rises).
Since internal fuses are hidden from view and most units contain at least 20 but can have as many as 100 elements, detecting one or two failed elements in a large internally fused capacitor bank requires very sensitive unbalance relaying equipment.
