Climate Change – What Do We Know, What Do We Not Know, and What May Be the Consequences For Electric Overhead Line Systems?
Abstract
The validity of global climate beinginfluenced by emissions of CO2 and other greenhouse gases
from human activities is now globally recognized. Although
the global temperature is expected to rise, and consequently
also precipitation amounts, many secondary effects are still
uncertain, concerning for example flooding, storm
frequencies, atmospheric icing and so on. However, many
electrical utilities around the world are already considering
preventive measures for their network, based on the
philosophy that proactive measures in the long run are
cheaper than taking extra costs for maintenance and repair
after expected increases in damage and outage frequencies.
