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

Abstract This publication is a continuation of many years of research on the development of the basis for building a unique resource-saving relay protection, which does not use current transformers to obtain information about the primary current. The authors propose to consider the possibility of building relay protection devices with the use of reed switches as sensitive elements. However, an important issue remains the study of reed switches parameters with the passage of time and the number of actuations and returns.
