ABSTRACT:
An Electric Power Line Monitoring System in which a single line measuring system station can measure all of the power parameters of both voltage and phase angle plus ambient and line temperatures. The measuring station can be secured to the power line without the need for shutting down the line. The measured data is transmitted from the measuring station on the power line to a ground receiving and data processing station. The system measures true RMS voltage and current values, RMS phase angle along with ambient and line temperatures which are digitized and transmitted through a digital fiber optic data link. The fiber optic data transmission line can be a flexible fiber optic cable assembly or a rigid fiber optic bushing assembly for supporting a long phase conductor that also contains a long resistive link of a voltage sensor voltage divider. The resistive link is constructed of materials that have a high precision resistance tolerance and low temperature coefficients of resistance that improved the accuracy of the voltage sensor.
