High-voltage experimental grounding rod used grounding wire should use bare copper wire.
The specific practice is: when installing and removing the grounding wire, there must be two people. When the equipment is no voltage, should be immediately after the inspection equipment grounding, and will be three-phase short circuit. Installation and removal of grounding wire should use insulated rod and wear insulated gloves. Installation of the grounding wire must be connected to the grounding end, and then connected to the conductor end, must be firmly in contact. Remove the grounding wire in the reverse order of installing the grounding wire.
Introduction of grounding wire:
Domestic electrical equipment due to poor insulation or use of humid environment, will lead to its shell with a certain ? Static electricity, serious electric shock will occur ? Accidents. In order to avoid accidents can be connected to a wire above the metal shell of the appliance, the other end of the wire into the earth, once the appliance leakage occurs when the grounding wire will be ? static electricity into the earth to release off.
Also for electrical maintenance personnel in the use of soldering iron soldering circuit, sometimes because of the soldering iron charged and breakdown damage to electrical appliances in the ? integrated circuits, which is more important. The use of computer friends will sometimes ignore the host shell grounding, in fact, to the computer host shell connected to a ground wire, to a certain extent, can prevent the phenomenon of crash.
In the power system grounding wire: is in order to have been out of power equipment and lines unexpectedly voltage to ensure that the staff of an important tool. According to the provisions of the Ministry, the grounding wire must be more than 25mm 2 bare copper wire made.
