Stds-WGC57.163 - Standards - Transformer Capability Under Geomagnetic Disturbance WG
|Working Group Chair||
|IEEE Program Manager|
This guide describes the effects of geomagnetic disturbances (GMD) on power transformers when there is the presence of geomagnetically induced current (GIC) in a power transformer. It establishes specification parameters and performance characteristics for power transformers to help minimize the risk and impact when GIC is present in the power system. The intent is to provide a background that can help evaluate the effect of GIC on a power transformer design and its GIC capability. This includes the evaluation techniques to determine the performance characteristics while under the influence of GIC. It does not include the effect of GIC on other power system devices beyond power transformers and accessories. It does not discuss mitigation techniques and mitigation devices such as neutral-blocking devices on equipment beyond power transformers and accessories.
IEEE C57.163-2015/Cor 1-2016 - IEEE Guide for Establishing Power Transformer Capability while under Geomagnetic Disturbances - Corrigendum 1
Clarified in this corrigendum to IEEE Std C57.163?-2015 is the derivation of the tie plate temperatures shown in Figure 13.
