American National Standard for Transformers - 230 kV and Below 833/958 through 8333/10 417 kVA,Single-Phase, and 750/862 through 60 000/80 000/100 000 kVA, Three-Phase without Load Tap Changing; and 3750/4687 through 60 000/80 000/100 000 kVA with Load Tap Changing-Safety Requirements
New IEEE Standard - Superseded.
This standard covers certain electrical, dimensional, and mechanical characteristics and takes into consideration certain safety features of 60-Hz, two-winding, liquid-immersed transformers rated as follows, and used for step-down or step-up purposes:
It is not intended that this standard apply to dry-type, regulating, pad-mounted, secondary-network, furnace, rectifier, or mine transformers.
The purpose of this project is to update C57.12.10 and to remove any reference to distribution transformers which will be covered in a new stand alone standard, C57.12.36.
