1 Scope This part of GB 1094 applies to dry-type power transformers (including auto-transformers) having values of highest voltage for equipment up to and including 40.5 kV and at least one winding operating at greater than 1.1 kV. The standard applies to all construction technologies. This standard does not apply to: ——gas-filled dry type transformers where the gas is not air; ——single-phase transformers rated at less than 5 kVA; ——poly-phase transformers rated at less than 15 kVA; ——instrument transformers; ——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 corresponding standards do not exist for the transformers mentioned above or for other special transformers, this part may be applicable as a whole or in parts. 2 Normative References The following standards contain provisions which, through reference in this part of GB 1094, constitute provisions of this part. For dated references, subsequent amendments to (excluding corrections to), or revisions of, any of these publications do not apply. However, parties to agreements based on this part are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the referenced document applies.
