IEEE Standard for Design and Performance Requirements for Bushings Applied to Liquid-Immersed Distribution Transformers

This standard covers electrical, mechanical, dimensional, and related requirements for non-condenser bushings used in liquid-immersed distribution transformers covered by IEEE Std C57.12.20™, IEEE Std C57.12.34™, IEEE Std C57.12.36™, and IEEE Std C57.12.38™ and that have basic impulse insulation levels (BILs) of less than or equal to 200 kV. These requirements are to be interpreted, measured, or tested in accordance with IEEE Std C57.19.00™ unless otherwise stated in this standard.
