IEEE Std C57.163-2023
IEEE Guide for Establishing Power Transformer Capability while under Geomagnetic Disturbances

Standard No.: IEEE Std C57.163-2023
Release Date: 2024
Published By: Institute of Electrical and Electronics Engineers (IEEE) US / IEEE
Latest: IEEE Std C57.163-2023
Replace: IEEE Std C57.163-2015

Scope: The effects of geomagnetic disturbances (GMD) on power transformers when there is the presence of geomagnetically induced current (GIC) in a power transformer are described. Specification parameters and performance characteristics for power transformers to help minimize the risk and impact when GIC is present in the power system are established. The intent is to provide a background that can help ...
