Abstract
An apparatus for removing harmonic noise from a power transmission line transmitting electricity at a primary frequency includes a filter and a controller coupled to the sensor and to an actuator-generator. The filter separates electricity at a harmonic of a primary frequency from the electrical signal transmitted by the power transmission line. The controller is configured to modulate consumption of electricity from the power transmission line. The consumption is controlled by electrical actuation of the actuator-generator, such that the electrical actuation of the actuator-generator causes consumption of electricity from the power transmission line at a harmonic of the primary frequency. The actuator-generator is coupled to an elastically deformable component, such that electrical actuation of the actuator-generator generates tension in the elastically deformable component.
