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.
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.
Each power system is unique and may respond to GMD conditions differently. Know how your assets will react to large events before they happen.
Need help on the geophysical modeling aspect of TPL-007-1?
Consult with our domain experts to answer any questions you may have getting started. We can also provide support for detailed analysis.
Understanding the GIC risk and how your system responds to that risk requires realistic electric field input.
AVERT can generate localized electric field maps based on actual measured regional data as input to your system modeling tools.
We are developing local risk indices that can be used to monitor the likelihood of GIC in real time.
