This standard covers electrical@ dimensional@ and related requirements for outdoor power apparatus bushings that have basic impulse insulation levels (BILs) of 200 kV and above. It provides specific values for dimensional and related requirements that are to be interpreted@ measured@ or tested in accordance with IEEE Std C57.19.00-1991. Bushings covered by this standard are intended for use as components of oil-filled transformers and reactors. For information on ratings not covered by this standard and for replacement bushings for oil circuit breakers@ refer to IEEE Std C57.19.01-1991.
