IEC\/IEEE 60214-2:2019 is published as an IEC\/IEEE Dual Logo standard and is intended to assist in the selection of tap-changers designed in accordance with IEC 60214-1 or IEEE Std C57.131 for use in conjunction with the tapped windings of transformers or reactors. Requirements, references and definitions relevant to either IEC 60214-1 or IEEE Std C57.131 are given and their use is described in Clause 4. It is also intended to assist in understanding the various types of tap-changers and their associated equipment available. These application guidelines cover on-load tap-changers (resistor and reactor types) and de-energized tap-changers. This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
\na) title has been updated from "Application guide" to "Application guidelines";
\nb) tap-changers for gas-filled transformers have been added;
\nc) description of typical circuits for regulation has been added;
\nd) description of basic arrangements of tapped windings with on-load tap-changers and de-energized tap-changers has been added;
\ne) types of tap-changers are explained in more detail (e.g. vacuum type on-load tap-changer) and new types have been added (e.g. step-voltage regulator, advance retard switch (ARS), on-load tap-changers for distribution transformers);
\nf) selection of tap-changers (on-load and de-energized) are described in more detail with respect to applications and parameters, which have to be considered (e.g. current wave shapes, operating pressure, temperature conditions, overloading conditions, continuous consecutive operations);
\ng) storage and installation has been considered;
\nh) field service, including commissioning, operation, maintenance and monitoring, has been considered;
\ni) safety aspects have been updated.<\/p>\n","protected":false},"excerpt":{"rendered":"
