This guide describes theoretical and practical ways to evaluate liquid-immersed power transformers, regulators, and reactors capabilities to withstand short-circuit currents resulting from external short-circuit faults. The equipment capabilities will be assessed based on calculations, design characteristics, construction techniques and material properties. The methods described are not mandatory and will not set forth requirements on how the transformer must be designed.
New IEEE Standard – Active. Guidance on determining and establishing short-circuit withstand capabilities of power transformers, regulators, and reactors is provided in this standard.
