This reduces the size and number of components needed in the SVC, although the conductors must be very large to handle the high currents associated with the lower voltage.

An SVC has no inertia compared to synchronous condensers and can respond extremely fast (2-3 cycles). This enables the fast control of reactive power in the control range. The location of SVC is important in determining its effectiveness. Ideally it should be located at the electrical center of the system or midpoint of a transmission line.
