Grounding: answers to questions

Series of notes and articles on interesting and frequently asked questions.

How to make a good grounding in rocky soil?

If the rock monolith has at least 0.8 - 1 meter of fine soil, electrolytic grounding can be used. This horizontal electrode in the form of a copper tube with perforations, inside which there is a mixture of special salts ... (continued on an invidividual page)

Copper coated ground conductors against black steel

Why copper-coated ground conductors serve much longer than ordinary black steel ones? ... (continued on an individual page)

What should be the depth of the grounding electrodes?

The information is the same everywhere, that the angles (vertical) must be 2.5 meters long. We have angles on metal base 6 meters long. I think to cut it in two 2-meter each... Question. It is critical that they will be 2 meters instead of 2.5? ... Or it is necessary to make it 2.5 meters? ... (continued on an individual page)

Do I need to bury a grounding conductor?

What is the difference, if the connecting wire between the grounding electrodes is laid at the depth of 0.5 m or on the surface? ... (continued on an individual page)

Grounding in the garage (electricity in the garage)

... I decided to change electricity completely starting from the exterior outlet box... COnsidering the peculiarities of the existing network, I began to study grounding systems offered in p. 1.7.3 EIC, consistently from one system to another ... (continued on an individual page)
  

Vertical ground conductor and its diameter

Will the grounding resistance reduce at the increase of ground conductor's diameter?
Will the service life of the ground conductor increase at the increase of its diameter... (continued on an individual page)      

The distance from the grounding to the pipeline

How far from the gas pipeline grounding should be mounted ... (continued on an individual page)
 

Grounding or progress?

We have no ground. . We mean we have ground under the feet, but no ground where to ground electric appliances. Many years ago, this ground was artificially made - 100- hundred- meters steel band was put over the icy bay with a tractor. The ice melted, the band sank, and a wire was welded to the part of the band that remained on the ground. Now we have electric 

 But that was long time ago and the band was ten times broken and there is no ground again. Because the ice ...(continued on an individual page)
 

Grounding. What is it and how to make it.

In the first part, I will describe the terminology, the basic types of grounding (purpose), and grounding requirements. 
In the second part I will tell a story about traditional solutions used at the construction of grounding devices, listing the advantages and disadvantages of these solutions. 
The third part will continue the second one in some way. It will contain description of the technologies used at the construction of grounding devices. Like in the second part, with all the advantages and disadvantages of these technologies ....(continued on an individual page)
