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™-19961)
c) Arc-suppression coils
d) Neutral-grounding devices (see IEEE Std 32™-1972)
e) Saturable reactors
f) Line-resonant reactors
g) Filter reactors
