Annotation

Replacement:

This part 2 of IEC 61558 applies to stationary or portable, single-phase or polyphase, aircooled safety isolating transformers, associated or otherwise, having a rated supply voltage not exceeding 1000 V a.c. and rated frequency not exceeding 500 Hz, the rated output not exceeding:

– 10 kVA for single-phase transformers;

– 16 kVA for polyphase transformers.

This standard is also applicable to safety isolating transformers without limitation of the rated output; however such transformers are considered as special transformers and are subjected to an agreement between the purchaser and the supplier.

he no-load output voltage and the rated output voltage does not exceed:

50 V a.c. r.m.s. and/or

120 V ripple-free d.c.

between conductors or between any conductor and earth.

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