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 publication presents the development and operating principle of an alternative resource-saving remote protection for electrical equipment connected to the cell of closed switchgears (CS), 110 kV and above. Here traditional measuring current transformers (CT) with metal cores are not used. Such current transformers have significant weight and dimensional parameters, as well as high cost. Scientific novelty of the work consists in the developed theory of construction of protection on inductive coils, based on measurement of electromotive force values in different modes, including points inside the cell of a closed switchgear. The use of inductive coils, proposed as a new element base in relay protection instead of traditional current transformers, is an innovative solution. It represents an excellent prospect for further development of relay protection. The scientific paper is purely research in nature. The result of the work is the creation of an alternative resource-saving distance protection on inductive coils.
