This International Standard deals with safety aspects of power transformers, power supplies, reactors and similar products such as electrical, thermal and mechanical safety. This standard covers the following types of dry-type transformers, power supplies, including switch mode power supplies, and reactors, the windings of which may be encapsulated or non-encapsulated : a) Stationary or portable, single-phase or poly-phase, air-cooled (natural or forced), isolating and safety isolating transformers, independent or associated, not forming a part of distribution networks and with the following characteristics: - rated supply voltage not exceeding 1 000 V a.c.; - rated supply frequency not exceeding 500 Hz; and complying with the following values, unless otherwise specified in the relevant part 2: . for isolating transformers: - rated output for single phase transformers, not exceeding 25 kVA, and for poly-phase transformers not exceeding 40 kVA. - no-load output voltage and the rated output voltage exceeding 50 V a.c., and not exceeding 500 V a.c, or 1 000 V a.c. to be in accordance with the National Wiring Rules or for a special application. for safety isolating transformers: - rated output for single phase transformers not exceeding 10 kVA, and for poly-phase transformers not exceeding 16 kVA. - no-load output voltage and the rated output voltage not exceeding 50 V a.c. between conductors, or between any conductor and protective earth. b) Transformateurs à enroulements séparés, autotransformateurs, transformateurs variables et petites bobines d'inductance, associés ou indépendants, à refroidissement par air (circulation naturelle ou forcée), fixes ou mobiles, monophasés ou polyphasés ne constituant pas une partie du réseau de distribution et présentant les caractéristiques suivantes: - tension primaire assignée ne dépassant pas 1 000 V en courant alternatif - fréquence primaire assignée ne dépassant pas 500 Hz; et satisfaisant les limites suivantes sauf spécification contraire dans la partie 2 appropriée: - une tension secondaire à vide ou une tension secondaire assignée pour les transformateurs associés ou indépendants n'excédant pas 15 kV courant alternatif et pour les transformateurs indépendants une tension secondaire assignée égale ou supérieure à 50 V courant alternatif - une puissance assignée n'excédant pas les valeurs suivantes: - 1 kVA pour les transformateurs monophasés - 2 kVAR pour les bobines d'inductance monophasées - 5 kVA pour les transformateurs polyphasés - 10 kVAR pour les bobines d'inductance polyphasées c) Stationary or portable, single-phase or polyphase, air-cooled (natural or forced), independent or associated power supplies and switch mode power supplies incorporating one or more transformer(s) of type a) or b), not forming a part of distribution networks and with the following characteristics: - rated supply voltage not exceeding 1 000 V a.c.; - rated supply frequency not exceeding 500 Hz; - internal operational frequency for power supplies not exceeding 500 Hz and for switch mode power supplies not exceeding 100 MHz; and with the following values, unless otherwise specified in the relevant part 2: . for power supplies and switch mode power supplies incorporating isolating transformers: - rated output for single- phase or polyphase power supplies or switch mode power supplies not exceeding 1 kVA; - no-load output voltage and the rated output voltage exceeding 50 V a.c. or 120 V ripple- free d.c., and not exceeding 500 V a.c. or 708 V ripple- free d.c., or 1 000 V a.c. or 1 415 V ripple- free d.c. to be in accordance with national wiring rules or for a special application; for power supplies and switch mode power supplies incorporating safety isolating transformers: - rated output for single- phase or polyphase power supplies and switch mode power supplies not exceeding 1 kVA; - no-load output voltage and rated output voltage not exceeding 50 V a.c.or 120 V ripple- free d.c. between conductors, or bet
