Why are capacitor banks important in substations?

Capacitor banks play a pivotal role in substations, serving the dual purpose of enhancing the power factor of the system and mitigating harmonics, which ultimately yields a cascade of advantages. Primarily, by improving the power factor, capacitor banks contribute to a host of operational efficiencies.

Do shunt capacitor banks exist in a substation?

At the same time, the presence of shunt capacitor banks impose constraints on apparatus present in a substation [1,2]. Currently, no specific configuration of shunt capacitor bank is recommended, grounded and ungrounded shunt capacitor banks can exist on the same transmission system.

What is a capacitor bank in a 132 by 11 kV substation?

In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.

Do capacitor banks reduce power losses?

Therefore, to improve system efficiency and power factor, capacitor banks are used, which lessen the system’s inductive effect by reducing lag in current. This, ultimately, raises the power factor. So, we can say that capacitor banks reduce power losses by improving or correcting the power factor. They are commonly used for these three reasons:
