AI Customer ServiceThe capacitor bank is installed close to the loadto provide reactive power locally. In a system in which a large number of small equipment are compensated, the reactive power demand may fluctuate, depending on the load. During off-peak load condition, the capacitor bank voltage may go up and hence overcompensation should be avoided.
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.
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.
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 function of fuses for protection of the shunt capacitor elements and their location (inside the capacitor unit on each element or outside the unit) is a significant topic in the design of shunt capacitor banks. They also impact the failure modality of the capacitor element and impact the setting of the capacitor bank protection.
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.
