Geomagnetic Induced Currents (GIC) can cause serious issues for power transformers leading to economic loss.
Transformers that may be at risk from GIC include:
- High voltage
- Grounded wye
- Y – Y
- Transformers interconnected with long transmission lines
Geomagnetic Induced Current Sensor
Dynamic Ratings GIC Sensor provide a means to sense, measure and communicate DC ground currents in harsh utility environments.
