EPRI GIC RF Monitor
Geomagnetically Induced Current (GIC) RF Monitor: This RF monitor measures a.c. and d.c. currents flowing in energized / deenergized conductors. Two different designs exist, one for rigid bus up to 10” in diameter, and one for conductors up to 2.5” in diameter. On-board algorithms also provide an analysis of the harmonics (up to the 7th). For energized conductor the GIC RF Monitor harvests power from the a.c. currents. For deenergized conductors either battery packs or solar panels are used depending on the required measurement rate.
