1 Scope This standard specifies the characteristics and tests for insulated bushings. This standard is applicable to bushings, as defined in Chapter 3, intended for use in electrical apparatus, transformers, switchgear and installations for three-phase alternating current systems, having highest voltage for equipment above 1000 V and power frequencies of 15 Hz up to and including 60 Hz. Subject to special agreement between purchaser and supplier, this standard may be applied, in part or as a whole, to the following: - Bushings used in other than three-phase alternating current systems; - Bushings for high-voltage, direct current systems; - Bushings for testing transformers; - Bushings for capacitors. Special requirements and tests for transformer bushings in this standard apply also to reactor bushings. This standard is applicable to bushings made and sold separately. Bushings which are a part of an apparatus and which cannot be tested according to this standard, and shall be tested with the apparatus of which they form part. 2 Normative References The following normative documents contain provisions which, through reference in this standard, constitute provisions of this standard. For dated reference, subsequent amendments to (excluding corrections to), or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this standard are encouraged to study whether the latest editions of these documents are applicable. For undated references, the latest edition of the normative document referred to applies.
