The electric power network is a fundamental system that is vulnerable to the effects of space weather and geomagnetically induced currents. Low-cost sensing technologies can be deployed to reduce the impact and improve mitigation measures towards space weather. Magnetic sensing using solid state devices has increased due to improved sensitivity, abundant availability and reduced costs. In this paper a low-cost geomagnetically induced current sensing system is introduced that detects currents at a fraction of the cost of existing technology in addition to overcoming applied challenges with previous work.
