Lightning injuries occur through direct strike, indirect strike, side flash, ground current, upward streamers, and blast effects. Postulated mechanisms for cardiovascular damage include electroporation, myocardial hemorrhage and necrosis, contusion, induced electric currents, catecholaminergic surge, coronary ...
Usually, the lightning current is the passed current, when a lightning strike contacts the ground resistance, which is about equal to twice the current incident wave that was transmitted. From: Inspection and Monitoring Technologies of Transmission Lines with Remote Sensing, 2017 ...
This requires that the current associated with the energy in the other stepped leaders also flows to the ground. The electrons in the other stepped leaders, being free to move, flow through the leader to the strike path. So when the strike occurs, the other stepped leaders are providing ...
Objects on the ground, _5_ taller things like mountains, buildings, trees and even people, can also build up an electric charge.When these charges meet, they _6_. The electric current(电流) runs rapidly from the cloud to the ground. This causes a lightning strike(电击). A flash of ...

3.At present more troubles in the transmit electricity line skit brake is caused by lightning strike,in the view of this phenomenon,combines with carrying out the lightningproof measures of 35 kV transmit electricity line in Xingtai Mine,the lightningproof technology was analysed.针对目前雷击引起的...
Thunderstorm - Lightning, Hail, Wind: A typical flash of cloud-to-ground lightning is initiated by electrical breakdown between the small positive charge region near the base of the cloud and the negative charge region in the middle of the cloud. The pre
animals and sets fire to homes and forests. It keeps aircraft grounded and damages power lines, wind turbines, and solar panel installations. However, little is known about what triggers lightning, and there is no simple technology for predicting when and where lightning will s...
If you are indoors, stay away from plumbing pipes (bath tub, shower). Lightning has the ability to strike a house or near a house and impart an electrical charge to the metal pipes used for plumbing. This threat is not as great as it used to be, because PVC (polyvinyl chloride) is ...
