How does the lightning protection of the world's highest building work?

How does the lightning protection of the world's highest building work?

One of the most popular external lightning protection devices is a single lightning rod-mast, installed in such a way that it creates a "protective field" that completely covers the required perimeter, excluding lightning striking the object. However, it is much easier to organize lightning protection for low buildings in this way than for high-rise buildings. But what about a situation when the height of the building is over 500 meters? We propose to consider this situation on the example of the tallest building in the world!
