What wire should be used for the grounding rod of high voltage experiment?

Bare copper wire should be used for the grounding rod of high voltage test.

The specific method is: when assembling and disassembling the grounding wire, there must be two people. When verifying that the equipment has no voltage, the maintenance equipment should be grounded immediately and the three phases should be short-circuited. Insulating rods and gloves should be used when installing and removing grounding wires. The grounding wire must be connected to the grounding end first, and then to the conductor end, and must be firmly contacted. The order of removing the grounding wire is opposite to the order of installing the grounding wire.

Introduction of grounding wire:

Because of poor insulation performance or humid environment, the shell of household appliances will be insulated to a certain extent. Static electricity, which can cause electric shock in severe cases? Accidents In order to avoid accidents, a wire can be connected to the metal shell of the electrical appliance, and the other end of the wire can be grounded. Once the electric appliance leaks, the grounding wire will connect it to the ground. Static electricity is brought into the earth and released.

In addition, when soldering a circuit with an electric soldering iron, the electric soldering iron sometimes breaks down and damages electrical appliances. Integrated circuit, this is more important. Friends who use computers sometimes ignore the grounding of the main chassis. In fact, connecting a ground wire to the main computer chassis can prevent the crash to some extent.

Grounding wire in power system: It is an important tool to ensure workers when voltage accidentally appears on the cut-off equipment and lines. According to the regulations issued by the Ministry, the grounding wire must be made of bare copper core wire of more than 25mm 2.
