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!
Use of rvt in capacitor bank
It depends upon at how much voltage level 400 kvar capacitor bank is used.
---- Capacitor banks used to improve power factor(lagging) of a circuit:: This is necessary since it causes saving in power and electricity bill in following ways: 1) As p.f rises, circuit currnt decreases and hence I2R losses reduce 2) Var consumption reduces There is no tool provided here to draw the ckt diagram:: U take on PFC(power factor correction bus), then connect switch fuse, then HRC fuse, then Contactor, then overload relay and finally the capacitor bank
Cable sizing is based on amperage of the load. The rating of the capacitor bank and the voltage at which it operated need to be stated to give an answer.
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.
You can calculate aggregate saving by using the power of compounding. The earlier you start saving, the faster you can aggregate or compound your existing savings in the bank.
It is calculated by knowing what the reactive power is that has to be countered.See related links below.
You need to explain what you mean by '4 mb'.
Use of rvt in capacitor bank
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.
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.

It doesn't ?

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).
