196-007-1 ABSTRACT A self contained hot stick mounted radio transmitting module may be temporarily pushed against the power conductor of an electrical transmission line. The module is capable of measuring the temperature of the conductor, and the tem- perature of the ambient air. It may also measure the electrical potential of the conductor. An alternative module is also capable of measuring current, potential, frequency and power factor (or the Fourier components thereof). The modules transmit these parameters to a local receiver where the data may be displayed. The receiver also may be connected by an appropriate data transmission link, to a power control center. The modules are donut shaped and open like a pair of jaws. One or more spring loaded temperature probes are located such that they may be pushed against a power line when a "donut" is mounted to a hot stick with the jaws open. Power to an open module is supplied by a battery. Power to a closed module, mounted on a conductor, may be supplied by the battery or by power derived from the conductor. A donut may be left on the power line for an indefinite time and the hot stick removed, or instantaneous measure- ments may be made with the hot stick attached, and the module then immediately removed. 196-007-1 The temperature probe of the present invention com- prises a pair of concentric spring loaded tubes. A beryllia insert is mounted between a temperature sensor and the power conductor.
