Full Description

Scope

This standard applies to series-connected dry-type air-core single-phase and three-phase outdoor or indoor reactors of distribution and transmission voltage class that are connected in the power system to control power flow under steady-state conditions and/or limit fault current under short-circuit conditions. Dry-type air-core reactors covered by this standard are self-cooled by natural air convection.With some restrictions, this standard is applicable to filter reactors, shunt capacitor reactors (used with shunt capacitor banks), and discharge current-limiting reactors (used with series capacitor banks).Annex A, Annex B, and Annex C are included to provide guidance.This standard does not apply to devices such asa) Shunt reactors (see IEEE Std C57.21(TM)-2008)b) Arc suppression coilsc) Neutral grounding devices (see IEEE Std 32(TM)-1972 [B21])d) Line resonant reactorse) High-voltage direct current (HVDC) smoothing reactors (IEEE Std 1277(TM)-2010 [B23])f) Forced cooled reactorsg) Line traps and radio interference (RI) filter reactors (ANSI C93.3-1995)

Purpose

The purpose of this standard is to define the requirements and test code for series-connected dry-type aircore reactors and, with some restrictions, filter reactors, shunt capacitor reactors, and discharge currentlimiting reactors.

Abstract

Revision Standard - Active.Recommendations are given for reactors intended for series connection, in both transmission and distribution systems, to control power flow under steady-state conditions and/or limit fault current under short-circuit conditions. Dry-type air-core reactors covered by this standard are self-cooled by natural air convection. With some restrictions, other reactors, including filter reactors, shunt capacitor reactors (used with shunt capacitor banks), and discharge current-limiting reactors (used with series capacitor banks) are also covered.
