This section is also applicable to small reactors with no rated capacity limitation, however, such small reactors are considered as special reactors and need to be determined through consultation between the user and the manufacturer. This section applies to small dry-type reactors. Its windings can be hermetically sealed or unsealed. This part does not apply to: — Reactors included in GB/T 10229; — Ballasts for tubular fluorescent lamps included in IEC 60920; — Ballasts for discharge lamps (excluding tubular fluorescent lamps) included in IEC 60922.
