What is the relationship between signaling equipment grounding and lightning protection

Relationship, it should be said that there is also a ground, that is, the ESD ground, although the three ground are playing in the ground, but the three ground can not be connected to a on the same, and now give an example:

1. For example, when the thunder, lightning at any time there is a possibility of striking in the lightning rod, if the equipment ground and lightning ground together, there can be equipment to be electrocuted, and even the possibility of accidents in the safety of human life.

2. The same ESD can not be more with the equipment ground and lightning connected together, because the ESD is connected to a 1M ohms resistance directly connected to the human body, if the equipment leakage, or lightning, there may be life-threatening, so ESD can not be more with the equipment ground and lightning connected together.

The above three ground at least 10 meters apart, and can not be shorted to each other.
