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.

I dont know.... may be due to save money
harmonic filter capacitor is used to filterize the unwanted heat created by a certain component like power supply. harmonics are voltage or currents that operates a certain frequency. john
Very carefully
improvement of power factor
A: Its purpose is to correct the power factor of the line.
Reduce the harmonic current in the electrical supply system.
In a substation there are many items. Circuit Breakers Disconnectors Earth Switches Current Transformers Voltage Transformers Surge Arrestors Power Transformers Insulators
Use of rvt in capacitor bank
A capacitor can store electrical charge, and a bank of them could store alarge charge. We sometimes set up a capacitor bank to store a large electrical charge for certain physics experiments. With the flip of a switch, we can "dump" all that electrical energy into a circuit to power up something. The pulse of power might be use do drive a big laser to punch a hole in a missile in a high arc, just to cite one example of the use of a bank of capacitors. In the electrical trade the capacitor bank is used for power factor correction. The capacitive reactance is used to offset the inductive reactance caused by inductive loads (motors). Motor loads can cause the power factor to drop to .8 or lower and for this the customer is penalized by an extra service charge. The goal is to have a power factor level above .9. where there is no surcharge from the power supply authority. The cost of installing a capacitor bank is soon payed off from the absence of the surcharge.
If your question is, "Can a capacitor bank reduce high loads in electrical systems?" Not really. In an AC system, a capacitor bank can be used to balance the complex power drawn by the load. If done correctly, this can reduce the current being drawn by the load. If done incorrectly, this can increase the current being drawn by the load. Look up "power factor correction" for more details.
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.
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!

It depends upon at how much voltage level 400 kvar capacitor bank is used.
