Yes, but the equipment often takes different forms. The best place to
get rid of circulating current in the transmission line is at the load,
before it causes additional line loss.

For signal lines a capicitance or an inductance often is formed by a
line stub.

For power lines a capacitance is often produced by an over-excited
synchronous motor or motors. Some constant speed loads are suitable for
sychronous machines. Such a machine drawing a leading current has been
called a rotary capacitor. Its current draw and capacitance are
controlled by its excitation.
Most induction motors and industrial loads have lagging currents. Power
factor correction requires the production of an offsetting leadng
current.
