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

Currently, frequency-regulated electric drives are widely used in technological installations of oil production. Along with technological advantages the use of controlled electric drive has negative consequences arising from higher harmonic currents in the mains, which can substantially increase the energy losses in electric networks. Invited to take these losses when evaluating the performance of controlled electric drive and reducing higher harmonic current. Pointed to the need for regulation not only voltage harmonics, but also current.
