It would not be wrong to say that humanity has never consumed so much electricity, and to make the paradox bigger, there is still a lack of energy. The sharp increase in consumption in the last couple of decades has created a lot of problems in electrical networks around the world. The optimization of costs and reducing.

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.
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.
Requests for reactive power compensation, voltage stability, and harmonic filter mitigation have increased as a result of the integration of renewable energies many other technologies into the electrical system. Capacitor banks are abundantly utilized in substations for improving overall power quality.
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
