This International Standard specifies the characteristics and tests for insulated bushings.
This standard is applicable to bushings, as defined in Clause 3, intended for use in electrical
apparatus, machinery, transformers, switchgear and installations for three-phase alternating
current systems, having highest voltage for equipment above 1 000 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 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 should be tested with
the apparatus of which they form part.
