Claim 0:
1. A device to be attached to an overhead power line for the purpose of manipulating movement of the overhead power line, the device comprising:
an electric power source;
a base, defining a base plane;
a clamp, secured relatively to the base, to be attached to a section of the overhead power line;
a flywheel, having a rotational axis;
an actuator, arranged to adjust the rotational axis of the flywheel in dependency of an actuator control signal;
an electric motor, arranged to rotate the flywheel about the rotational axis in dependency of a motor control signal;
an acceleration sensing device, secured relatively to the base, providing an acceleration signal; and
a controller device, arranged to receive the acceleration signal and to provide the motor control signal and the actuator control signal, the controller device being configured to:
in an overhead power line stabilizing mode, calculating the motor control signal and the actuator control signal in dependency of the acceleration signal in such a way as to minimize the acceleration signal,
in an ice removal mode, calculating the motor control signal and the actuator control signal in dependency of the acceleration signal in such a way as to cause fluctuations in the acceleration measured by the acceleration sensing device;
wherein the ice removal mode is different from the overhead power line stabilizing mode.
