capacitor banks is to use the measured neutral current. The neutral current is equal to the sum of the three phase currents that flow through the capacitor bank. If a fuse opens or if a switch fails to open or close on one or two phases, the neutral current increases from nearly zero to the bank''s rated phase current. As a result,

If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.
