FIELD: physics; electricity.
SUBSTANCE: system consists of transmitting unit mounted on transmission tower and is connected to line phase through external resistor to provide data signaling to electric power substation. Line wiring weight load data for icing is received by magnetoelastic ice pickup. Power is supplied to circuit from single-phase transformer. Receiving unit mounted on substation is also connected to line phase through similar resistor. Transmitting unit transfers to substation a series of pulses at frequency of less than 1 Hz, pulse number within this series being determined by thickness of ice on wire, received by receiving unit and displayed on digital indicator.
EFFECT: increased reliability of work and accuracy of measurements.
