How Do I Install Grounding Rod
(1) Before laying the grounding rod, you should first dig a pit about one meter, and then pile the grounding rod into the earth. The top of grounding rod should leave a margin about 0.2m to connect grounding wire. Grounding rod's depth into the ground should be no less than two meters. For rocky areas, the grounding rod's body can be buried horizontally, and the depth of embedding should be no less than 0.6m.
(2) The connection among grounding rods should be solid. The top of grounding rods should be connected as a whole, with 2.5 ~ 3m spacing. The number of vertical grounding rod should be at least two. The connecting parts of the ground rod need to be welded.
During Installation, What Should I Do To Ensure Safety
Electrical equipment shell can have a high ground voltage when not properly operated. To prevent the equipment and grounding rod from generating sparks and causing incidents, we need take the following measures:
(1) All electrical equipment, as well as building metal structures, should be grounded.
(2) Electrical equipment's joints should be firmly pressed. All electrical equipment connection part should be crushed firmly, and apply measures to prevent poor contact.
(3) In order to prevent the occurrence of electrical discharge when measuring the grounding resistance, the measuring shall be carried out in a building free of explosion risk, or the measuring end button shall be taken outdoors for measurement.
(4) Conductive cross section of a wire should be wide enough.
After Installation, Can I Just Call It A Day and Leave It Be?
No. Maintenance of the grounding device is very important to keep its functionality. Usually we need to pay attention to two major aspects:
(1) Measure ground resistance regularly
Do a measurement of the grounding resistance at least once every two years. This need to be carried out in the season that soil resistivity is at highest.
(2) Annual check of grounding rod
According to the seasonal changes, inspect the exposed part of the grounding device at least once a year. The inspection should include the following aspects:
a. The integrity of grounding wire. Check for corrosions and fractures.
b. The connectivity of the grounding bar and the grounding rod.
c. Whether the grounding wire is in good contact with the electrical equipment and the grounding bar and grounding rod.
If there are any loose ends, we should repair it in a timely manner.
