IEEE PC57.154/D8, March 2022 IEEE Draft Standard for Liquid-Immersed Transformers Designed to Operate at Temperatures Above Conventional Limits Using High-Temperature Insulation Systems.
Institute of Electrical and Electronics Engineers (IEEE)
Scope
Covered in this standard are all liquid-immersed distribution, power, and regulating transformers that are designed to operate at temperatures that exceed the normal thermal limits of IEEE C57.12.00 under continuous load, in the designed average ambient, and at rated conditions. Specific requirements and guidance in the design, testing, and application of the transformers covered within the scope ...
