- Description
Geomagnetically induced current (GIC) measurements made at two 3 phase, 3 limb transformers, operating in the Halfway Bush substation in Dunedin, New Zealand have been analyzed during the May 2024 Gannon Storm. GIC measurements were combined with very low frequency radio wave AC harmonic measurements made nearby, and reactive power measurements made at key points in the substation. This study focuses on the 11 May, 00–14 UT period when geomagnetic activity was high and the 220 kV transformers...
