High Voltage DC Active Current Injection to Simulate Geomagnetically Induced Currents in New Zealand
Space Weather, Volume 24, Issue 3, March 2026.Abstract This study investigates the effects of geomagnetically induced currents (GIC) on New Zealand's electrical infrastructure via an intentional ground injection of direct current (DC) from a high voltage DC converter station. GIC manifests as quasi‐DC currents within power systems, potentially causing transformer saturation, increased reactive ...

Modeling Geoelectric Fields in Ireland and the UK for Space Weather Applications [PDF]
Space Weather, 2019 AbstractGeoelectric fields at the Earth's surface caused by geomagnetic storms have the potential to disrupt and damage ground‐based infrastructure such as electrical power distribution networks, pipelines, and railways. Here we model geoelectric fields in Ireland and the UK during both quiet and active time intervals of geomagnetic conditions using ...
