Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The article presents an analysis of emergency situations on high- and extra-high-voltage overhead transmission lines (OTL) in the Republic of Kazakhstan and examines the factors that reduce the stability of the power system. Based on KEGOC JSC operational data for 2019–2023, the main causes of failures have been identified — long service life, climatic loads, and electrochemical corrosion of metallic structural elements of overhead transmission lines. Theoretical studies in the field of diagnostics and protection of 500 kV overhead transmission lines are reviewed, including monitoring and fault prediction methods. The necessity of developing an intelligent combined protection system integrated into the digital Smart Grid architecture is substantiated.
