Results of monitoring the geomagnetic variations at the Magadan and Paratunka observatories

Izvestiya, Physics of the Solid Earth, 2011
We analyze the magnetic tensor and tipper data in the interval of periods from a few minutes to a few hours for the geomagnetic time series of 2007–2008. The frequency responses, the polar diagrams, and the real and imaginary induction arrows which reflect the effects of geoelectric heterogeneities are calculated.

Monitoring program protects transformers from geomagnetic effects

IEEE Computer Applications in Power, 1992
An application program that was written on a control center energy management system (EMS) to monitor transformers in a bulk power system for the effect of geomagnetic-induced current (GIC) flows is described. The monitoring program is based on summing the Mvar around a transformer and subtracting from that result the Mvar that theory predicts is being
