Reliability modeling of high-voltage power lines in a sharply continental climate [PDF]

E3S Web of Conferences, 2020
One of the important elements of the high-voltage transmission line is 110 kV, the damage of which leads to under-supply of electricity, i.e. reducing the reliability of the lines.

Communication Characteristics of Faulted Overhead High Voltage Power Lines at Low Radio Frequencies

Energies, 2017
This paper derives a model of high-voltage overhead power line under fault conditions at low radio frequencies. The derived model is essential for design of communication systems to reliably transfer information over high voltage power lines. In addition,
