A flexible probe is provided for detecting time-varying magnetic fields produced in an electric generator. The flexible probe is adapted to be disposed within an air gap formed between an iron stator and a rotatable rotor. An electrostatic shield layer is formed on a front face of the probe and a printed circuit forming at least one coil is printed on the back face. When the flexible probe is used for detecting time-varying magnetic fields, a voltage is induced in the coil when the coil is exposed to a time-varying magnetic field.

A ground based conductor motion sensing apparatus is provided for remotely sensing movement of electric power transmission lines, particularly as would occur during the wind induced condition known as galloping. The apparatus is comprised of a motion sensor and signal generating means which are placed underneath a transmission line and will sense changes in the electric field around the line due to excessive line motion. The detector then signals a remote station when a conditioning of galloping is sensed. The apparatus of the present invention is advantageous over the line mounted sensors of the prior art in that it is easier and less hazardous to install. The system can also be modified so that a signal will only be given when particular conditions, such as specific temperature range, large amplitude line motion, or excessive duration of the line motion, are occurring.
