scope:

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 C57.16™²)

c) Arc-suppression coils (see IEEE Std C57.32™)

d) Neutral-grounding devices (see IEEE Std C57.32)

e) Saturable reactors

f) Line-resonant reactors

g) Filter reactors (see IEEE Std C57.16)

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.
