Capacitor Bank Definition: A capacitor bank is a collection of multiple capacitors used to store electrical energy and enhance the functionality of electrical power systems. Power Factor Correction: Power factor correction involves adjusting the capacitor bank to optimize the use of electricity, thereby improving the efficiency and reducing costs.
After the capacitor is connected in parallel, the current of the capacitor willoffset part of the inductance current, so that the inductance current decreases, the total current decreases, the phase difference between the voltage and the current decreases, and the power factor increases. 2.
