When designing the system of the grading of the building, I define the level of groundingforlightening of the building. Then I design the lightning conductor of the roof and the ground wire.
在进行防雷接地设计时，先确定了其防雷等级，再对屋顶进行了避雷带的设计和负一层接地设计。

To test the site electricity conductivity according to the grid, and provide the information for the grounding and lightening proof design.
