Abstract: Self contained radio transmitting modules are mounted on power conductors at various places along electrical transmission lines. The modules are capable of measuring current, voltage, frequency and power factor (or the Fourier components thereof), the temperature of the conductor and the temperature of the ambient air. Up to fifteen modules may transmit on a single channel to a single local receiver. Each module transmits at intervals which are an integral number. The intervals between transmissions of all modules do not have a common factor and the average interval is the desired transmission rate.

Abstract: A toroidal sensor module having a metallic outer skin and mounting means for installation upon and removal from an energized power conductor providing synchronized measurements of electrical parameters. In one embodiment the module is adapted to measure the values of voltage, current and phase angle of the conductor upon which it is mounted, and to communicate data representing such values to a ground station in the vicinity of the sensor module. The voltage and current are sensed simultaneously to provide time-synchronized readings with respect to voltage zero crossings from which the phase relationship is determined. The metallic skin of the module may be either capacitively or electrically coupled to the conductor for purposes of making conductor voltage measurements. The toroidal housing is divided into two, mutually insulated sections to prevent an electrical short circuit loop on any peripheral path on the housing extending through both sections, thereby allowing the electromagnetic field of the conductor to be coupled to sensing elements within the housing.
