The planned UHV grid in India scheduled for 2025. noted that, according to the result, all transformers under the influence of the edge effect are shown to have suffered from relatively large GICs. Many of these substations suffer from GIC of over 400 A, among them, the largest GIC is 442.9 A. As the power grid continues to expand in scale, the UHV power grid has begun to adopt a standardized design for transmission lines to enhance power transmission efficiency. Thus, larger GICs will occur in networks with higher voltage levels when the geomagnetic storm is assumed to be the same, and the GIC magnitude is mainly determined by the structure of the grid.
