|Publication Date:||26 September 1991|
This standard covers electrical, dimensional, and related requirements for outdoor powerclass apparatus bushings that have basic impulse insulation levels (BILs) of 110 kV and higher. It provides specific values for dimensional and related requirements that are to be interpreted, measured, or tested in accordance with IEEE C57.19.00-1991 133.
Bushings covered by this standard are intended for use as components of oil-filled transformers, oi-filled reactors, and oil circuit breakers.
