IEEE 62032-2005 pdf download Guide for the application, specification, and testing of phase-shifting transformers
1. Overview
1.1 Scope
This guide covers the application, specification, theory of operation, and factory and field testing of single-phase and three-phase oil-immersed phase-shifting transformers (PSTs).
This guide is limited to matters particular to PSTs and does not include matters relating to generalrequirements for power transformers covered in existing standards, recommended practices. or guides.
1.2 Purpose
The terminology, function, application, theory of operation and protection, and design of PSTs are notcovered by existing transformer standards and guides. The purpose of this document is to provide guidanceto those specifying,designing, and using PSTs.
2. References
This standard shall be used in conjunction with the following publications. When the following standards aresuperseded by an approved revision, the revision shall apply.
NOTE The user’s atention is drawn to the fact that the publications referenced below have no precise equivalent amongpublications issued by IEC. Normally, it is the practice of the lEC to include equivalent EC standards for standards publishedby other organizations at the regional or national levels. However, following comments made by national committees on14/491/FDlS. it has been determined that as no lEC publications exist that are exactly equivalent to lEEE standards. it wouldbe misleading to provide references to similar EC publications. This standard therefore includes references in this clause toIEEE standards only.

3. Definitions
All definitions, except as specifically covered in this guide shall be in accordance with IEEE C57.12.80-1978and The Authoritative Dictionary of lEEE Standards Terms, Seventh Edition (B101.-
3.1 advance phase angle: The phase angle expressed in degrees that results when the load (L) terminalvoltage leads the source (S) terminal voltage
3.2 excitation-regulating winding: A two-core phase-shifting transformer (PST) design in which the mainunit has one winding operating as an autotransformer that performs both functions listed under excitationand regulating winding of a two-core PST
3.3 excitation winding: The winding of a phase-shifting transformer (PST) that draws power from thesource to energize the PST.
3.4 excited winding of a two-core phase-shifting transformer (PST): The winding of the series unit thatis excited from the regulating winding of the main unit.
3.5 L terminal: The L terminal is used to measure the voltage phase-shift angle when compared to the S terminal of the phase-shifting transformer (PST).
3.6 main unit of a two-core phase-shifting transformer (PST) : The core and coils that furnish excitation to the series unit.
