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 should a capacitor bank be installed at the injection substation?
Therefore, for the customers to enjoy supply so that power utility can as well improve its revenue generation, it is important to install a capacitor bank at the injection substation to neutralize the reactive power on the line from source (Adesina and Ebere, 2017).
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.
What is a distribution capacitor bank?
Distribution capacitor banks 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.
How do capacitor banks work in underground distribution systems?
For underground distribution systems, capacitor banks areinstalled in pad-mounted enclosures as small, distributed installations that are connected to main-primer feeder circuits at a considerable distance from the substation. These distributed banks can be fixed on the circuit or switched on and off as dictated for system stability.
