Abstract
This article proposes a method for assessing the dynamic availability of telecommunications network equipment, taking into account seasonal variations in grounding device parameters. A mathematical model has been developed that accounts for the influence of soil temperature and humidity, thunderstorm activity, freeze-thaw processes, and corrosion on soil resistivity and grounding resistance. It is shown that in the spring, when the ground has not yet completely thawed and thunderstorm activity is already increasing, equipment availability decreases due to deterioration in grounding parameters. The need for continuous monitoring of grounding device parameters to promptly identify deviations and maintain the required level of reliability of telecommunications equipment is substantiated.
