Static Var Compensators
A capacitor element cannot give a stepless variation: therefore, if a smooth continuous variation is needed over the whole range A-A′ in Figure 41.8(b), a capacitor bank having a rating to give at least the current I C must be connected and the variable element must be inductive, with a rating to give a current at least equal to I C + I L.
