Ground Rod Resistance To Earth

Chemical treatment of soil is a good way to improve earth electrode resistance when you cannot drive deeper ground rods because of hard underlying rock for example.

Ground rod resistance to earth.

Treatment of the soil. The procedures for earth resistance testing are referenced in ieee standard no. The lower it is the better job it does. For instance if a ground rod is driven into a very rocky and dry area it may not conduct electricity into the ground well.

2 point dead earth method. Run the wire to your test location. Go back to ways to improve earth electrode resistance 3. If you do not have one already you can easily install a ground rod for your home.

In some instances ground rods can be installed in areas where the earth has a lot of resistance. Step 1 connect your length of wire to a metal stake in the ground. Make sure that you have stripped back the insulation from both ends of the wire to allow for a good connection. Ground ring ground rods.

If this is the case for your ground rod the best solution is to drive a different rod into a different location. Four of the most common methods of ground resistance testing used by test technicians are discussed below. The function of any ground rod is to dissipate the current that is recovered in any faulty electrical circuit near your house to the earth surrounding the ground rod. To properly test the resistance of a ges you must follow some simple rules.

The rule is that the lower the resistance it has the better job it does. You can only do this by using the fall of potential method with a three terminal earth ground resistance tester. You should measure the resistance of an electrode with respect to the surrounding soil in the area. It is beyond the scope of this manual to recommend the best treatment chemicals for all situations.

For example the national electric code requires no greater than 25 ohms of resistance in a ground system. For a safe electrical system your ground rod resistance should have a very low resistance value.
