IEEE Std C57.19.01 pdf download IEEE Standard for Performance Characteristics and Dimensions for Power Transformer and Reactor Bushings
This standard covers electrical, dimensional, and related requirements for outdoor power apparatus bushingsthat have basic impulse insulation levels (BILs) of 150 kV and above. It provides specific values fordimensional and related requirements that are to be interpreted, measured, or tested in accordance with IEEEStd C57.19.00TM .1 Bushings covered by this standard are intended for use in free air as components of liquid-immersed transformers and reactors.
