Capacitor Applications in Distribution Systems
Assuming that all capacitor banks are of equal size, The c-ratio of eq. (2) is the ratio of the capacitor current to the current at the beginning of the line. For eq. (3), n is the number of capacitor banks; for n=1, then c = 2/3, which means the optimal amount of capacitance is 2/3 of the total reactive load.

What does the Voltage Rating on a Capacitor Mean?
Take note that a capacitor''s voltage rating is not the voltage that the capacitor will charge up to, but only the maximum amount of voltage that a capacitor should be exposed to and can store safely. For the capacitor to charge up to the desired voltage, the circuit designer must design the circuit specificially for the capacitor to charge up to that voltage.
