HD-3 computing method of radius of protection used in Rolling Sphere Method, according to solid geometry and Plane geometry principle,then the calculation formula is listed by graphical method, Based on the actual situation, the relevant formulas are calculated.
The protection range between two lightning rods is to roll two balls on the ground to both sides of the lightning rod, And get it which contact the two spheres of the intersection of the line.

Company is committed to in the lightning protection technology research and development, successively in lightning protection, lightning online monitoring and intelligent connected grid field made 7 national patents, in the industry first proposed the concept of lightning intelligent protection system for data management. Proposed a ground technology international patent through the PCT phase, entered the United States approval stage. Initiated the new field of active lightning protection, at the same time, creatively solved the grounding problems and lighting protection problems of high resistivity area (rock landform), arid area(desert landform).
