The following small and special dry-type transformers are not covered by this standard:
- single-phase transformers rated at less than I KVA and polyphase transformers rated at less
5kVA;
- instrument transformers (covered by IEC Publications 185: Current Transformers, and
186: Voltage Transformers);
-transformers for static convertors (covered by IEC Publications 84: Recommendations for
Mercury-arc Convertors, 119: Recommendations for Polycrystalline Semiconductor
Rectifier Stacks and Equipment, and 146: Semiconductor Convertors);
- starting transformers;
- testing transformers;
-traction transformers mounted on rolling stock;
-flameproof and mining transformers;
-welding transformers;
-voltage regulating transformers;
- small power transformers in which safety is a special consideration.
Where IEC standards do not exist for the transformers mentioned above or for other special
transformers, this standard may be applicable as a whole or in parts.
With the publication of this standard, the requirements of IEC Publication 76 apply to dry-
type transformers only in so far as they are referred to in this standard.
