6 FAQs about [Asmara Substation Capacitors]
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.
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.
How does a capacitor bank work?
The installation of the capacitor bank in the substation adopts a double-star configuration. In this arrangement, capacitors are strategically positioned to create a star connection, and two such double-star-connected capacitor configurations are subsequently connected in parallel.
What is a double star connected capacitor bank?
In this arrangement, capacitors are strategically positioned to create a star connection, and two such double-star-connected capacitor configurations are subsequently connected in parallel. The configuration of this capacitor bank is visually depicted in Figure 2.
