If you want 100kVAR from a capacitor bank, you must install a 100kVAR capacitor bank. If what you're asking is related to how much capacitance it will take to offset a poor power factor, it is directly related to your load, and cannot be answered without more details - for power factor correction, you don't want to over correct (you would be buying too much equipment, and it could actually make your power factor look worse), so load profiles must be taken into account. Can the capacitors be switched on automatically, or must they be manually switched? What voltage level? The best way to determine this is to discuss with your local power company. They usually have people on staff that analyze this sort of thing on a regular basis, and if they don't, they could at least point you in the right direction.
It depends what it's for. If it's for power-factor improvement, then it is normally connected in parallel with the load.
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.
Use of rvt in capacitor bank
Normal power is the multiplication of current to combination of resistive and reactive or capacitive load. From the vector sum of Apparent power minus real power we can get reactive power(KVAr), which is basically lagging power due to reactive load. This will be the exact rating of capacitor bank. You can find it by cos $ of apparent power.
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.

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.
improvement of power factor
If you are talking about a capacitor bank used for power-factor improvement, then it is rated in reactive volt amperes (var). Otherwise, it is rated in farads (F).
Capacitors are used to improve an inductive load's power factor towards unity. The power factor before and after adding the capacitor bank depends entirely on the inductive/capacitive values involved.

It is calculated by knowing what the reactive power is that has to be countered.See related links below.
It's not peculiar. That's a property of capacitors.
Capacitor banks can improve the power factor if the load is leading, which is unusual. Typically in substations capacitor banks are employed to reduce over voltage.
The most common method of improving the power factor of a load is to connected a capacitor or capacitor bank, of appropriate reactive power (expressed in reactive volt amperes), in parallel with the load.
