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.
What are example of capacitive load?

How do you size a current limiting reactor for a capacitor bank?

Why Capacitor bank should be switched off when DG is in operation?
When generation kicks on, it can cause system voltage to rise, fall, or stay the same. Capacitors banks are used to help boost system voltage. Inductor banks are used to pull system voltage down. In many situations, capacitor banks may be required to kick ON when generation kicks on - some wind turbines "suck in VARS", or act like inductors while pushing out power. This causes system voltage to sink, and must be counteracted using capacitors. In your situation the distributed generation may be causing unacceptable voltage increases with the capacitor bank online.
What is the use of capacitor bank?
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.
What is the use of reactors in capacitor bank panels?
Reduce the harmonic current in the electrical supply system.

Is capacitor bank can reduce high load in the electrcal system?
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.
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.
What is the use of rvt in capacitor bank?

Why are capacitors required to be in capacitor banks?
Capacitor banks are used to control the power factor in a power system. By connecting suitable capacitors the power factor can be controlled / maintained at a desired level. The requirement of a capacitor changes as the load changes dynamically. The same amount of capacitors can not maintain the desired power factor all the time. To be able to connect only the required number of capacitors, multiple (bank of capacitors) capacitors are included in a system. An automatic controller senses the actual power factor and connects and disconnects the capacitors from the bank as required
Why do transformers needs 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.
What is the Funcition of capacitor bank in electrical system?
Its function is to counteract the inductive component of the load to reduce the apparent power -- to minimize the phase difference of the voltage and current phasors. The electrical utility company charges more for low power factor, which is defined as the ratio of real to apparent power. Please see the related link. =================================
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!

How many current drawn in 400 kvar capacitor bank?
It depends upon at how much voltage level 400 kvar capacitor bank is used.
Why you install capacitor bank in electrical room?
Capacitor banks are installed in the electrical room to improve the power factor which is related to the inductive load caused by motors etc . The capacitors create a capacitive load which subtracts against the inductive load thereby improving the power factor. Most power utilities have penalties when your power factor drops below a certain value.
