Lightning Impulse Ageing of HV Cable Insulation

, 2009
Lightning impulses can lead to accelerated ageing of extruded cables. Electrical behaviour of a dielectric material when experiencing a lightning impulse is different to that for DC or power frequency applied voltages.

Lightning Strike Victim Data [PDF]

About 40 million lightning strikes hit the ground in the United States each year. But the odds of being struck by lightning in a given year are less than one in a million, and almost 90% of all lightning strike victims survive.

Modeling lightning strikes to tall towers

In this chapter, we present a review of recent progress in the modeling of lightning strikes to tall structures. Since some tall structures are struck by lightning several tens of times per year, they can be used as ground-truth to measure and calibrate ...
