Lightning protection grounding device

Lightning protection grounding device
The combination of grounding body and grounding wire used to conduct lightning current and dissipate it into the earth.

The grounding device is an important part of the lightning protection device. The grounding device discharges the lightning current to the ground, limiting the voltage of the lightning protection device to the ground from being too high. In addition to the independent lightning rod, the lightning protection grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements. The grounding for the purpose of quickly introducing the lightning current into the earth to prevent lightning damage is called lightning protection grounding.

The anti-grounding device includes the following parts:

1. Lightning receiving device: metal rods (lightning terminals) that directly or indirectly receive lightning, such as lightning rods, lightning protection belts (nets), overhead ground wires and lightning arresters, etc.

2. Grounding wire (down conductor): The metal conductor used to connect the lightning receiving device and the grounding device.

3. Grounding device: the sum of the grounding wire and the grounding body, which is used to conduct lightning current and dissipate it into the ground.
