m, the undercurrent protection shall be blocked using the capacitor bank circuit breaker open status signal.To provide protection against reconnection of a charged capacitor to a live network and ensure complete ca acitor discharging before breaker reclosing, the relay shall include breaker re
Moreover, the protection settings for the capacitor bank unfold systematically, elucidating the process of selecting the current transformer ratio, calculating rated and maximum overload currents, and determining the percentage impedance for fault MVA calculations.
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.
When designing a capacitor bank, many factors must be taken into consideration: rated voltage, kvar needs, system protection and communications, footprint and more. These factors govern the selection of the capacitor units to be used, along with proper grouping of these units.
The uniqueness of this scenario lies in the decision to install the capacitor bank at the 11 KV voltage level, even though the factory receives power from the grid at a higher voltage level of 132kV, with an approved connection capacity of 12 megawatts.
Capacitor bank is usually controlled by the microprocessor based device called power factor regulator. Beside, segment installation practice demands protection for capacitor banks. In this case, capacitor banks are connected to the busbars, which supply a group of loads. What’s good in this solution // No billing of reactive energy.
