Capacitor bank can also be switched ON and OFF depending upon the Amp of the load. The function of a capacitor bank is to neutralize reactive power in the system, measured in KVAR or MVAR. The switching of the capacitor bank depends on the reactive power load.
Switchable Capacitor Bank Definition: A switchable capacitor bank is defined as a set of capacitors that can be turned on or off to manage reactive power in an electrical system. Purpose: The main purpose of a switched capacitor bank is to improve power factor and voltage profile by balancing the inductive reactive power in the system.
These banks are typically installed in the primary network of a power sub-station, helping improve the power profile of the entire system, including transformers and feeders. Capacitor Bank can be controlled automatically depending upon voltage profile of the system.
Power factor can be used as another system parameter to control a capacitor bank. When the power factor of the system comes below a predetermined value the bank is automatically switched ON to improve the pf. A capacitor bank can also be controlled by a timer.
Reactive Power Management: Switched capacitor banks help in reducing overall reactive power, which enhances system efficiency and stability. Automatic Control: These banks can be controlled automatically based on system voltage, current load, reactive power demand, power factor, or timers.
Since the voltage of the system depends upon the load, hence capacitor may be switched on just below a certain preset voltage level of the system and also it should be switched OFF above a preset higher voltage level. Capacitor bank can also be switched ON and OFF depending upon the Amp of the load.
