本标准适用于额定值超过500 kVA的所有油浸式或干式、单相或三相、户外或室内并联电抗器。本标准也适用于静态无功补偿器（SVC）中使用的可控硅控制的并联电抗器。本标准不适用于其他设备，例如:a）并联电抗器、500kVA及以下设备；b）限流电抗器（见IEEE Std C57.16（TM）-2011）；c）消弧线圈d）中性点接地设备（见IEEE Std 32（TM）-1972）；e）饱和电抗器f）线路谐振电抗器g）滤波电抗器

This standard applies to all oil-immersed or dry-type, single-phase or three-phase, outdoor or indoor shunt reactors rated over 500 kVA. This standard also applies to thyristor-controlled shunt reactors used in static var compensators (SVCs). This standard does not apply to other devices such as the following: a) Shunt reactors, 500 kVA and smaller b) Current-limiting reactors (see IEEE Std C57.16(TM)-2011) c) Arc-suppression coils d) Neutral-grounding devices (see IEEE Std 32(TM)-1972) e) Saturable reactors f) Line-resonant reactors g) Filter reactors
