Organization: IEC
Publication Date: 1 June 2000
Status: inactive
Page Count: 40
ICS Code (Transformers. Reactors): 29.180
scope:

This part of IEC 61558 applies to stationary or portable, single-phase or poly-phase, air-cooled (natural or forced) general purpose small reactors, including alternating current, premagnetised and current compensated reactors, independent or associated, having a rated supply voltage not exceeding 1 000 V a.c. or d.c. and rated frequency not exceeding 1 MHz, the rated power not exceeding

- 2 kVAR a.c. (2 kW d.c.) for single-phase reactors;

- 10 kVAR a.c. (10 kW d.c.) for poly-phase reactors.

This standard is also applicable to small reactors without limitation of the rated power; however, such small reactors are considered as special reactors and are subjected to an agreement between the purchaser and the supplier.

This standard is applicable to dry-type small reactors. The windings may be encapsulated or non-encapsulated.

This standard does not apply to

- reactors covered by IEC 60289;

- ballast for tubular fluorescent lamps covered by IEC 60920;

- ballast for discharge lamps (excluding tubular fluorescent lamps) covered by IEC 60922.

NOTE 1 For small reactors filled with liquid dielectric or pulverised material such as sand, additional requirements are under consideration.

NOTE 2 In locations where special environmental conditions prevail, particular requirements may be necessary.

NOTE 3 Normally, small reactors are intended to be associated with equipment for functional requirements of the equipment or requirements by the installation rules or by other appliance specifications.

NOTE 4 Small reactors incorporating electronic circuits and components are also covered by this standard.

NOTE 5 The safety insulation may be provided (or completed) by other parts or features of the equipment, such as the body.

NOTE 6 Small reactors for particular applications will in the future be covered by complementary normative annexes.
