[@muhdsolihin2641]

should be disconnecting earth cable from house to ground chamber first. so you will get the purest ground resistance.

[@pankajmishra43]

Hiiii... You mean, first disconnect the earth cable from earth pit?? OR Can we shutdown the entire system before measuring earth resistance?? Pls guide

[@Sim_Tiby]

Disconnect the earth cable.

[@DiReal_Donclassy]

Of course he must have done that before starting the test otherwise the resistances of home equipment will distort the result

Hi sir. You did a very informative video thanks. I've a question for you.In the video you did the test on a big compound. I'm in a terrace house and the compound is very limited. I can't pull the yellow and red cable that long..only 3-4 meters to the nearest soil. Will it affect the reading? Please advice thks.

[@rictorrictor888]

In that situation ..You can try nearest area to ground the spike ..

[@rictorrictor888]

You have to maintain distance. Please read my other comments. Get permission from neighbours.

[@ahmedbelazi2318]

Thank you for the effort made in the video.... I have a question... Is it true that the yellow wire is supposed to be an extension of the red wire, meaning on one line to give the reading... Why change in yellow only and should it be changed in red? ??

[@iranweranga225]

Is there a specific number of times that earth resistance testing should be done for a specific area? (like number of times per meter squard)

[@fauzibafana9089]

Can i know whether before the individual earth rod being tested you have to remove the connection of the earth rod from the rest.

[@gniraj8501]

I am also have same question.

[@30mAkills]

Yes it should be disconnected from service. If the voltage is more than 10 it will destroy the meter and also give false reading. Please read the user manual reg the max voltage limit that the meter will work safely in energised service without disconnection.

[@robertotrinanes1744]

What about the grounding rod resistance?each rod shall be tested and removed all connected cable before the test of total resistance grounding.

[@mohamadasriabdulazid4784]

Not really it depends on the situation and regulations of the country. We usually do it at the installation state, we check each time the rod is inserted to the earth. These guys in the video are doing inspection for application form.

[@neilblenkinsop2613]

To individually test the earth rod disconnect tape from earth rod

[@gohpoikheng6030]

May i know why the cable for current is longer than the voltage?

[@raemondbradford1629]

When current is injected into the earth, then the voltage will change around the location of injection. The voltage reference cable spike needs to be some distance from the points where current is injected or removed, in order to try and find a location with minimal disturbance of earth voltage potential.

[@30mAkills]

@@nasiadomary4893 1. If possible increase the depth of electrode. 2. Insert another electrode at a distance of at least twice the buried depth of 1st electrode and link both at top. Eg.: If 1 st electrode buried depth = 3 M then second electrode should be installed at a distance of minimum 6 M away and both should be linked with wire or strip at the top. 3. Wet the pit by watering because dry earth is a bad conductor. Note : Chemical electrodes are fraud work. Hope all this helps.

Hi sir I have a doubt. Could you please tell me the difference between 2 point, 3 point method. In megger it has 4 terminals C1, C2, P1, P2. how to measure earth pit resistance?

[@30mAkills]

Short C1 and P1 and connect to electrode under test. P2 is for potential and C2 is for current spike. This is known as 3 point or Fall of Potential method. 4 terminals method is for testing soil as per Wenner method. This is for civil guys and not for electrical guys. Reg 2 point earth pit resistance testing: In India we don't/cant use this method because our public water supply is thru PVC pipes which is non conductor. Hope this helps.

[@AutodidactEngineer]

The test should be done preferably during the driest season to prevent moisture from ruinning your values!

I have a question, engr. Why is it required in the earth resistance tester manual to damp the surroundings?

Use a combination of vertical and horizontal grounding! My tip would be get copper/or in poorer countries galvanized pipe works well enaugh and install it in conjunction with galvanized steel bar/ or do the same but with copper if you can afford it!

What about the distance btn the spikes does it matter !?

[@anthonykihanga2881]

5 meters up to 10 meters it depends on soil type

[@30mAkills]

Thumb rule for current spike distance from electrode = Minimum 8 to 10 times the buried depth of earth electrode. Eg., If earth electrode is 3 M long then C spike should placed about 24 to 30 M distance. This is to avoid '"zone of influence"' factor. Most manufacturers wont tell this because the distance will affect their tester sales in city and town areas where space is congested. So they suggest 5 M and 10 M which will not yield correct value. I challenge Kyoritsu in this matter.
