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.
Generally the capacitor rating of a bank are decided on the load factor.ie higher the KVAR higher the capacity.KVAR is the reactive power in which load angle differs with the load variation.If we know load factor multiply it by the sine angle which gives us the capacity of the cpapcity of the load bank.

Use of rvt in capacitor bank
The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.

The shape of a capacitor has no meaning to the circuit. What matters is the capacitance, the voltage rating, and the current rating. 35uf is not the same as 45uf.
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.
It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.
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 change in potential difference across a capacitor is determined by the amount of charge stored on the capacitor and the capacitance of the capacitor. The relationship is given by V = Q/C, where V is the potential difference, Q is the charge stored on the capacitor, and C is the capacitance.
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.
