Abstract

See full text

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.
