Geomagnetic Disturbance Risk

Asset-specific GIC Risk Assessment







GICs flowing along electric power transmission lines are produced from induced electric fields on the surface of the Earth.

Transformers exposed to even moderate currents due to GIC experience premature aging. Over time they may overload and melt, shedding excess power to neighboring transformers and systems.

Understand the GIC risk.


Assess the Risk


The orientation of long transmission lines, the core type of transformer equipment and the grounding characteristics of substations all play a role in the amount of GIC that is experienced by an individual power system during a given storm.

Once the GMD hazard conditions are known for a reference event or an example storm, the GIC induced in a long line can be estimated for specific system layouts.

CPI's domain expertise and innovative modeling tools can help you assess your individual risk.

What is the impact of GMD on my system?



Each power system is unique and may respond to GMD conditions differently. Know how your assets will react to large events before they happen.
