APPARATUS FOR MONITORING THE CONDITION OF A POWER TRANSMISSION LINE Russian patent published in 2022 - IPC G01R31/08 

FIELD: testing.

SUBSTANCE: invention relates to monitoring the condition of power transmission lines located in remote and hard-to-reach locations. Substance: apparatus for monitoring the condition of a power transmission line comprises a tool for the attachment to the power transmission line; electrically connected, a power source, a wireless communication module consisting of a transceiver and an antenna and ensuring two-way communication via repeaters of low-orbit satellites, a main controller, and an interface for connecting a power transmission line condition sensor. The transceiver ensures two-way communication via repeaters of low-orbit satellites at 300 to 450 MHz frequencies. The antenna provides a 360° width of the horizontal directivity pattern.

EFFECT: higher stability of two-way communication signal of the transceiver with repeaters of low-orbit satellites at any position thereof relative to the apparatus and when exposed to severe weather conditions, drastic changes in the local topography, or interference from tree branches.
