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.
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.
However, if a capacitor bank is still connected, it can cause high reactive power, worsening the power factor instead of improving it. It’s not always cost-effective to keep a capacitor bank on all the time. Capacitor provide reactive power opposite to that of inductors, which helps neutralize inductive reactive power from loads.
These capacitor banks are switched on either manually (using circuit breaker or switches) or semi-automatically by a remote-controlled contactor. Automatic power factor correction (APFC): For loads that require varying reactive power, APFC is used. Also, under light load conditions, a fixed capacitor provides a leading power factor.
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.
