The Lightning Phenomenon
|
From Alltec Corporation
Alltec World Headquarters has always been committed to Quality and continuous improvement. We are pleased to share with you that Alltec World Headquarters is in the process of having its quality system certified and registered as compliant with ISO 9001:2000. Alltec Corporation introduces its new ground resistance monitoring product, the GRM2000, which addresses concerns on operator safety and system efficiency. Lightning, an awesome and terrifying natural phenomenon, is really nothing more than an electrical discharge that happens to be at an enormous voltage. Lightning equalizes a difference of electrical potential, whether it is between a cloud and the ground, between two clouds, or between two different areas of the same cloud. Due to various mechanisms in storm cloud formation, such as the rising and falling of air currents carrying moisture and ice particles, the storm cloud generates an electrical charge at its base. Charged regions in a thundercloud create conductive ionization channels through the atmosphere called “stepped leaders,” while an opposite electrical charge or "shadow" accumulates on the ground below.
