6 FAQs about [Capacitors for substations]
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.
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.
What happens if a substation does not have a capacitor?
Without capacitors, load circuits will operate at reduced voltage, motors will run slower and overheat, lights will not burn as bright, relays in process industries will drop out, etc., creating end-user system disturbances. Capacitors extend the range of substations by allowing feeder circuits to have longer runs of cable.
Why are shunt capacitors used in EHV substations?
Usually extra-high voltage (EHV) lines are used to transmit bulk power from remote generations to load centers. These long lines tend to produce significant voltage drops during peak loads. Therefore, shunt capacitors are used at the EHV substationsto provide reactive power. Sometimes these capacitor banks are switched as and when required.
What is a distribution capacitor?
Distribution capacitors areinstalled close to the load, on the poles, or at the substations. Although these capacitor units provide reactive power support to local load, they may not help reduce the feeder and transformer losses. Low voltage capacitor units are cheaper than high voltage capacitor banks.
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:
