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.
