Manufacturers usually include built-in fuses in each capacitor element. If a fault occurs in an element, it is automatically disconnected from the rest of the unit. The unit can still function, but with reduced output. For smaller capacitor banks, only these built-in protection schemes are used to avoid the cost of additional protective.

Customer ServiceCapacitor 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.
3. Short circuit protection In addition to the relay functions described above the capacitor banks needs to be protected against short circuits and earth faults. This is done with an ordinary two- or three-phase short circuit protection combined with an earth overcurrent relay.
There are mainly three types of protection arrangements for capacitor bank. Element Fuse. Bank Protection. Manufacturers usually include built-in fuses in each capacitor element. If a fault occurs in an element, it is automatically disconnected from the rest of the unit. The unit can still function, but with reduced output.
Capacitor banks require a means of unbalance protection to avoid overvoltage conditions, which would lead to cascading failures and possible tank ruptures. Figure 7. Bank connection at bank, unit and element levels. The primary protection method uses fusing.
The protection scheme for a typical 12.6 MVAR (2 × 6.3 MVAR connected in double Wye) capacitor bank with external fuses and a series detuning reactor is show in Figure 3. A time-overcurrent relay, device 51, with an inverse or very inverse characteristic, is used for capacitor-bank fault protection.
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.
