Abstract

This part 2 of IEC 61558 applies to stationary and portable, single-phase and polyphase, aircooled (natural or forced) independent and associated separating transformers, having a rated supply voltage not exceeding 1000 V a.c, a rated frequency not exceeding 500 Hz, and a rated output not exceeding: - 1 kVA for single-phase transformers; - 5 kVA for polyphase transformers. Transformers covered by this standard may only be used where double or reinforced insulation between circuits is not required by the installation rules or by the appliance specification.
