How To Make A Ground Wire?

In the grounding system, grounding wire production and installation are significant. The following is the production and installation of grounding wire or grounding electrode.

1, resistance is less than 4Ω.
The grounding resistance size can define the size of the grounding current. The smaller the value of the grounding resistance, the smaller the grounding voltage of the grounding device. This means that the grounding resistance value’s size, marking the good and bad performance of the equipment grounding.

2.Measurement of resistance
Grounding resistance is generally available ammeter-voltmeter, bridge method, grounding resistance measuring instrument, etc. to measure, are currently using dropping opposition measuring device to measure, this method is convenient and straightforward.

Generally speaking, the grounding wire buried in the ground depth should not be less than 2 m. In particular, places to install grounding electrodes, if the centre does not reach 2 m, should be placed around the grounding electrode salt 8 kg, about 30 kilograms of wood carbon, and add water to reduce the grounding resistance.

If using two and more than two grounding electrodes, the interval between the poles is less than 0.5m to reduce the earth’s dissipation resistance. In the strongly corrosive soil, copper-plated or galvanized grounding electrode should be used. Simultaneously, the grounding electrode should not be buried in the garbage layer and ash layer area, and the grounding electrode laid in the ground should not be painted to avoid excessive grounding resistance.
