本标准适用于配电和输电电压等级的串联干式空心单相和三相户外或室内电抗器，这些电抗器连接在电力系统中，用于在稳态条件下控制功率流和/或在短路条件下限制故障电流。本标准涵盖的干式空心电抗器通过自然空气对流进行自冷却。 由于有一些限制，本标准适用于滤波电抗器、并联电容器电抗器（与并联电容器组一起使用）和放电限流电抗器（与串联电容器组一起使用）。 附录A、附录B和附录C旨在提供指导。 本标准不适用于以下设备: a） 并联电抗器（见IEEE标准C57.21（TM）-2008） b） 消弧线圈 c） 中性点接地装置（见IEEE Std 32（TM）-1972[B21]） d） 线路谐振电抗器 e） 高压直流（HVDC）平滑电抗器（IEEE Std 1277（TM）-2010[B23]） f） 强制冷却反应堆 g） 线路陷波器和无线电干扰（RI）滤波电抗器（ANSI C93.3-1995）

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 as a) Shunt reactors (see IEEE Std C57.21(TM)-2008) b) Arc suppression coils c) Neutral grounding devices (see IEEE Std 32(TM)-1972 [B21]) d) Line resonant reactors e) High-voltage direct current (HVDC) smoothing reactors (IEEE Std 1277(TM)-2010 [B23]) f) Forced cooled reactors g) Line traps and radio interference (RI) filter reactors (ANSI C93.3-1995)
