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.
Types of Protection: There are three main protection types: Element Fuse, Unit Fuse, and Bank Protection, each serving different purposes. Element Fuse Protection: Built-in fuses in capacitor elements protect from internal faults, ensuring the unit continues to work with lower output.
The unbalance protection should coordinate with the individual capacitor unit fuses so that the fuses operate to isolate the faulty capacitor unit before the protection trips the whole bank. The alarm level is selected according to the first blown fuse giving an early warning of a potential bank failure.
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.
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.
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. Reference // Protection Application Handbook by ABB
