This part of IEC 61558 deals with the safety of small reactors for general applications. Unless otherwise specified, from here onward, the term transformer or reactor covers small reactors. This part is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) general purpose reactors including alternating current, premagnetised and current compensated independent or associated reactors. The rated supply voltage does not exceed 1000 V a.c. or 1500V ripple-free d.c., the rated supply frequency and the internal operational frequencies do not exceed 1 MHz. The rated power does not exceed: - 25 kVAR a.c. (25 kW d.c.) for single-phase reactors, - 50 kVAR a.c. (50 kW d.c.) for poly-phase reactors. This part is applicable to reactors without limitations of the rated power subject to an agreement between the purchaser and the manufacturer. This part is applicable to dry-type reactors. The windings may be encapsulated or nonencapsulated. This part does not apply to: - reactors covered by IEC 60289; - ballast for tubular fluorescent covered by IEC 61347-2-8; - ballast for discharge lamps (excluding tubular fluorescent lamps) covered by IEC 61347-2-9.
