By publication of this standard, no position is taken by the IEEE with respect to the existence or vali

If a patent holder or patent applicant has filed a statement of assurance via an Accepted Letter of Assurance, then the statement is listed on the IEEE-SA Website at http:/standards.ieee.org/about/sasb/patcom/patents.html. Letters of Assurance may i

Users of this standard are expressly advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is

Introduction This introduction is not part of IEEE Std C57.158-2017, IEEE Guide for the Application of Tertiary and Stabilizing Windings in Power Transformers. I

45、n all mature industries, as for instance the electric power supply industry, there is always a knowledge that is commonly applied, even though its fundamentals have not been summarized in a single, comprehensive source. In most cases, impact of such “missing links” is very minor, and more important

46、issues become privileged for development into standards, as resources are naturally scarce. This document deals with the subject of application of stabilizing windings in modern electric power systems, where some issues with wye-wye-connected transformers emerging in the early days were solved with

47、practical sense by adding extra components in transformers, without an exact account of all real and potential benefits. Part of the fundamentals for those applications is a tacit, empirical knowledge, with arbitrary interpretations of successful or unsuccessful events giving rise to a series of “ru

48、les,” from which very different versions are implemented. The purpose of this document is, first, to synthesize the fundamentals for contemporary application of a technical solution, and second, to review and present to the industry a more organized set of application rules and recommendations. The

49、IEEE working group that developed this application guide started working as a task force in 2009, and originally developed a proposed new subclause 5.11.1.2 for IEEE Std C57.12.00-2014. The purpose of that specific subclause was to standardize interpretation for the power and/or thermal rating required for stabilizing windings, also known as buried tertiaries. In this document, a wider scope is offered, including power systems application concepts, zero-sequence currents, nonlinear magnetization of ferromagnetic cores, a more repeatable and user-friendly definition f
