The increase in demand for energy consumption in the world is the basis for the formation of many scientific and practical projects in this field. In particular, the increase in the level of load on overhead power lines requires accurate and timely monitoring of the energy system. This article analyzed the issue of remote monitoring of the condition of low-voltage overhead power lines in laboratory conditions using an electronic micro current sensor. The results of the proposed research can be applied to the remote monitoring of the distribution network of low-voltage overhead power lines, which is of great importance for monitoring the condition of the lines, efficient use of energy, and intelligent maintenance.

One of the tasks of mobile operators when covering a 5G network is to ensure reliability in various parts of the network, since new services and applications require not only high bandwidth, but also uninterrupted service. This article is a presentation of a reliable protection scheme based on an ultra-dense passive optical network with wavelength division multiplexing (UD-WDM PON) for the transport layer of the 5G network, i.e. for the forward/feedback section.

This paper shows the scheme of operation, the features of one of the antennas widely used in wireless networks-the logoperiodic dipole antenna. The antenna consists of two components located on both sides of the dielectric layer according to the established rule, and their elements together form dipoles. In the CST studio environment, the antenna efficiency is analyzed and output based on parameters such as the antenna parameter S11, the radiation pattern.
