Description

GIC-xxxz transducers are able to measure DC currents in the presence of higher levels of AC. This enables accurate measurement of Geomagnetically Induced Currents (GIC) on power grids, and of the DC components potentially present in Photo-Voltaic system and inverters. The device operates over a wide dynamic range and maintains low-level accuracy even after a large over-range. The GIC’s inherently low residual effect eliminates the need to degauss in all but extreme circumstances. The split-core enclosure, with captive hardware and outdoor rating, makes installation easy and does not require circuit interruption.

Why measure Geomagnetically Induced Currents (GICs)

Geomagnetically Induced Currents (GICs) can result from geomagnetic storms—a type of space weather event in which Earth's magnetic field is rattled by incoming magnetic solar material. Most GICs are triggered by coronal mass ejections, or CMEs, which interact with the magnetic field around Earth and cause it to rattle. The quick-changing magnetic fields create GICs through a process called electromagnetic induction. GICs can flow through railroad tracks, underground pipelines, and power grids. In extreme cases, they can cause blackouts.
