IEEE C57.164-2021 PDF Download

The IEEE C57.164-2021 standard offers guidance and recommendations for determining the ability of liquid-filled power transformers, regulators, and reactors to withstand short-circuit currents. The standard covers both theoretical and practical approaches to assessing the equipment's resistance to external short-circuit faults.

The evaluation process involves considering factors such as calculations, design characteristics, construction techniques, and material properties of the equipment. However, it is important to note that the methods described in the standard are not mandatory and do not impose specific design requirements for the transformers. Instead, they serve as a reference for determining the short-circuit withstand capabilities of the equipment.
