This standard applies to all liquid-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 C57.16TM2) c) Arc-suppression coils (see IEEE Std C57.32TM) d) Neutral-grounding devices (see IEEE Std C57.32TM) e) Saturable reactors f) Line-resonant reactors g) Filter reactors (see IEEE Std C57.16TM) Purpose This standard specifies the requirements@ terminology@ and test code for liquid-immersed and dry-type shunt reactors rated over 500 kVA and for thyristor-controlled shunt reactors used in SVCs.
