IEEE C57.16

Abstract

This standard applies to <em>series-connected</em> 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 <em>limit</em> fault current under short-circuit conditions. Dry-type air-core reactors covered by this standard are self-cooled by natural air convection. <br>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. <br>This standard does not apply to devices such as <br>a) Shunt reactors (see IEEE Std C57.21&#8482;-2008⁾¹ <br>b) Arc suppression coils <br>c) Neutral grounding devices (see IEEE Std 32&#8482;-1972 [B21])² <br>d) Line resonant reactors <br>e) High-voltage direct current (HVDC) smoothing reactors (IEEE Std 1277&#8482;-2010 [B23]) <br>f) Forced cooled reactorsg) Line traps and radio interference (RI) filter reactors (ANSI C93.3-1995) <br><strong>Purpose</strong> <br>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. <br>¹ Information on references can be found in Clause 2. <br>² Numbers in brackets correspond to the numbers in the bibliography in Annex G.
