The Challenge of High-Building Lightning Protection

Modern buildings are getting higher and closer to the sky. On World Meteorological Day, a group of experts in Guangzhou, China carried out an academic discussion. They released a study, shows that high buildings are more likely to intercept the surrounding lightning's downward leader, resulting in increased number of strikes on high buildings.

The study was carried out jointly by the Chinese Academy of Meteorological Sciences and the Guangdong Meteorological Bureau in Pearl River New City, Guangzhou, where most of high buildings (more than 300 meters) are concentrated. By the end of the study, scientists found out that before a lightning strike occurred, the upward leader generated by buildings around 100m height is relatively short, usually between a few meters to less than a hundred meters. However, when building height reaches 400 meters, the upward leader can be as much as the building height. If the buildings are even higher, the upward leader can be more than one kilometer, longer than their own height.

In a word, it is easy for high buildings to intercept the surrounding lightning. This is the reason why high buildings were struck by lightning much more.
 

An Innovative Solution – ESE Lightning Rod

Traditionally, we would install a conventional Franklin lightningrod for building's lightning protection. However, these conventional lightning rods are not so effective in high buildings as in lower buildings, because of the significant gap in upward leader length. Franklin lightning rod's upward leader is relatively short, probably shorter than upward leader produced by high building itself, makes it useless for lightning strike protection.

The ESE lightning rod solves this dilemma perfectly. With the help of early streamer emission mechanism, the ESE lightning rod can generate a much longer upward leader, making it more superior over Franklin rods on high buildings. When ESE is installed on high building, it can guarantee a longer upward leader than building itself, greatly increase the chance of receiving lightning strike, and provide a sound protection of the building.
