I believe that capacitor banks are used to improve the power factor of lagging loads. They do this by reducing the reactive load.
Capacitor banks cannot improve the resistive component of a load, and they cannot improve the power factor of leading loads.
Here is an explanation of the technical terms used:
A leading load is one where current leads voltage. Lagging or reactive loads have current which lags the voltage. Resistive loads have a current which is in phase with (not leading or lagging) voltage.
If a capacitor bank is used on a circuit where current lags voltage, it decreases the current lag, improving the power factor. If a capacitor bank is used on a leading or resistive load, it will increase the leading time and make the power factor worse.
A leading load is one that is already too capacitive.

∙ 13y agoA capacitor bank is a grouping of several identical capacitors interconnected in parallel or in series with one another. These groups of capacitors are typically used to correct or counteract undesirable characteristics, such as power factor lag or phase shifts inherent in alternating current (AC) electrical power supplies. Capacitor banks may also be used in direct current (DC) power supplies to increase stored energy and improve the ripple current capacity of the power supply.

∙ 9y agoIn high voltage situations, a capacitor bank stores a charge of electric, similar to a battery, so that when a sudden large draw is put on the line, thus causing the voltage to drop, it will do a temporary release of stored energy into that line causing the sustained energy level to be more stabilized.

∙ 8y agoA Capacitor Bank is a group of several capacitors of the same rating that are connected in series or parallel with each other to store electrical energy . The resulting bank is then used to counteract or correct a power factor lag or phase shift in an alternative current (AC) power supply. They can also be used in a direct current (DC) power supply to increase the ripple current capacity of the power supply or to increase the overall amount of stored energy.
There are some specific advantages of using capacitor bank such as,
a) It reduces line current of the system.
b) It improves voltage level of the load.
c) It also reduces system Losses.
d) It improves power factor of the source current.
e) It reduces load of the alternator.
f) It reduces capital investment per mega watt of the Load.

Purpose of capacitor bank on a sub-station electrical room?
The primary reason for a capacitor bank in an electrical substation is for power factor correction. There may also be some secondary purpose for the capacitor bank but the primary reason is power factor correction.

How do you reduce spike current?
by using capacitor on the line we can reduce spike current or we can use a capacitor bank for the rated line capacity.
What are the ways to stop lagging current?
use more impedense load and use suitable capacitor bank with the load.
What is the use of reactors in capacitor bank panels?
Reduce the harmonic current in the electrical supply system.
Why capacitor bank using reeactor?
Series reactors may be used in switching in capacitor banks. These are used to minimize the transient voltage spikes on the system resulting from switching in a capacitor bank.
How do you calculate Kwh saving after installing capacitor bank?
Adding a capacitor bank makes absolutely no difference whatsoever to the amount of energy consumed (in kilowatt hours). The capacitor bank might reduce the load current, but this does not affect the amount of energy consumed. Anyone who tries to sell you a 'capacitor bank' in order to save you energy is selling a SCAM!
