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.
by using capacitor on the line we can reduce spike current or we can use a capacitor bank for the rated line capacity.
Use of rvt in 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!
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.
capacitor bank
It depends upon at how much voltage level 400 kvar capacitor bank is used.
It doesn't ?
A capacitor can be charged using a battery by connecting the positive terminal of the battery to one terminal of the capacitor and the negative terminal of the battery to the other terminal of the capacitor. This creates a flow of electrons from the battery to the capacitor, storing electrical energy in the capacitor.
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).
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.
a capacitor bank
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.
