NEN-EN-IEC 61558-2-10 deals with the safety of separating transformers with high insulation level and separating transformers with output voltages exceeding 1000 V. Transformers incorporating electronic circuits are also covered by this standard. Unless otherwise specified, from here onward, the term transformer covers separating transformers with high insulation level and separating transformers with output voltages exceeding 1000 V a.c or 1500 V d.c . This Part 2-10 is applicable to stationary or portable, single-phase or polyphase, air-cooled (natural or forced) independent or associated dry-type transformers. The windings may be encapsulated or non-encapsulated. This standard is applicable to transformers and power supply (linear) with internal operational frequencies not exceeding 500 Hz. This standard used in combination with Part 2-16 for switch mode power supply units (SMPS) is also applicable to power supplies with internal operational frequencies higher than 500 Hz. Where the two requirements are in conflict the most severe take precedence. The rated supply voltage does not exceed 1 000 V a.c., and the rated supply frequency and the internal operating frequency do not exceed 500 Hz. The rated supply voltage does not exceed 1000 V a.c., and the rated supply frequency and the internal operating frequency do not exceed 500 Hz. The rated output does not exceed: - 25 kVA for single-phase transformers; - 40 kVA for polyphase transformers. This Part 2-10 is applicable to transformers without limitation of the rated output subject to an agreement between the purchaser and the manufacturer. Where applicable the no-load output voltage or the rated output voltage: - does not exceed 1000 V a.c. or 1500 V d.c. for separating transformers with high insulation level; - does exceed 1000 V a. c or 1500 V d.c. and does not exceed 15 000 V a.c. or 15000 V d.c. for separating transformer with output voltage exceed 1000 V. This Part 2-10 is not applicable to: - transformers covered by IEC 60076-11; - neon transformers covered by IEC 61050 and - power supplies and converters for use with or in products according to IEC 61347-2-10. This Part 2-10 is not applicable to external circuits and their components intended to be connected to the input terminals and output terminals of the transformers. Transformers covered by this Part 2-10 are used only in applications where double or reinforced insulation between circuits is not required by the installation rules or by the end product standard.
