IEEE Guide for Paralleling Regulating Transformers
Control methods of paralleling regulating transformers are described and compared in this guide. The control methods include: master/follower, circulating current, power factor, circulating reactive current and negative reactance methods. Operating philosophy descriptions, sample wiring diagrams, typical operational variations, the provision of adequate backup protection, and typical misapplication consequences are presented. This guide does not apply to phase-shifting regulating transformers
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
