Power and Pipelines (Ground Systems)
The dynamical space
environment may even be felt at home. Power-line failures and
corrosion effetcs observed in pipelines on Earth may be the direct
result of Space Weather induced effects!
Pipelines suffer from
corrosion effects since geomagnetically induced currents when
flowing from the pipe into the soil may increase the corrosion
rate. The associated voltage can disturb pipeline surveys and the
The most well-known effect of a geo-magnetic storm was when
geomagnetically induced currents caused a black-out for about nine
hours in the province of Quebec in March
1989. Furthermore a transformer in the USA was destroyed in this
storm. For more information about Space Weather effects on power
systems, see (Lund Space Weather Center introduction).
Lessons learned from Solar
Cycle 22 concerning geomagnetic storms and impacts on power systems
can help us in reference to the upcoming Solar Cycle 23.
