scope:

This part of IEC 60076 applies to the following types of reactors: - shunt reactors; - series reactors including current-limiting reactors, neutral-earthing reactors, power flow control reactors, motor starting reactors, arc-furnace series reactors; - filter (tuning) reactors; - capacitor damping reactors; - capacitor discharge reactors; - earthing transformers (neutral couplers); - arc-suppression reactors; smoothing reactors for HVDC and industrial application; with the exception of the following reactors: - reactors with a rating less than 1 kvar single-phase and 5 kvar three-phase; - reactors for special purposes such as high-frequency line traps or reactors mounted on rolling stock. Where IEC standards do not exist for small or special reactors, this part of IEC 60076 may be applicable as a whole or in part.
