Hiiii... You mean, first disconnect the earth cable from earth pit?? OR Can we shutdown the entire system before measuring earth resistance?? Pls guide
One more thing what's the distance between two consecutive Earth Pit what's the exact standard if you can please explain this the the minimum distance between two consecutive Earth pits
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? ??
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.
when lightning strikes the earth doesn't the surge enter the house via the earth wiring? If so isn't it dangerous, probably better not to have any earthing system at all?

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.
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?
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.
Saya nak tanya, bukankah testing dibuat semasa pemasangan rod sahaja (sebelum kita sambungkan dengan earth DB atau sebelum sambung ke perlindungan kilat)
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!
green wire is for grass. grass is green. make sense right? put green wire on grass and see resistance of grass. grass is green, green wire is green too. make sense right? right.
It depends on your country standards. But the Best is the nearest to 0 ohms which is imposible to get 0 ohms. Also there are many methods to make the measurraments, it depends on your country standards too.
Good country with laws and people that know a well earth ground safe tere life, reduce EMC, lower the body contact voltage, ... Wow well electrician = You controlled (only optical) the ground connection boxes around the house. For the beginning well done. I hope you measure the low resistance later to be sure that the connections are not corroded. Fine work und knowledge ! Well done. Attention your result is influence of the premium earth groundind metal in the earth. Keep the measuring line far away or you get worse results. 2.10 Ohm is very very low = perfect but in my country I start thinking why is it so low ? Where is the fault to get these brilliant results ? Very wet earth ? Under the measuring line = really no water pips, no powerlines, no other pipes/metallsheets , ... What is hidden under the bid concret by the 2nd Spike movement. Testing the earth voltage = well done you know the users manual ! Perfect We use different instruments in europe (english version form page 37 to page 72) www.dehn.de/store/f/27628622/EBA/1805_060583_GEOHM_Messger%C3%A4t.pdf And other brands.

It need not be inserted. Wrap the spikes in wet towel and place them horizontally on the concrete floor with weights (stone) placed on the sack. Wet the whole area by watering.
Why to use this device with long cables and sticks while THEORETICALLY one can get more relevant results using any household electric appliance like, say, Incandescent light bulb, a mulimeter and the old good Ohm's Law? One terminal of the bulb is connected to live (hot), the other to earth and the current is measured. Divide voltage by current and subtruct the bulb's resistance and the result is the earth resistance. What is wrong in such approach?
I get what you mean and yes you can get accurate measurement through ohms wall but use a proper load resistor that is large enough to limit the current so the damage you will cause on the ground rod is limited.
Kedalam nya sehingga rod gak bisa masuk lagi..baru di uji..jika masih tidak mendapat kan bacaan yg dikehendaki..buat point baru sehingga mendapat bacaan yg paling rendah
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.

@@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.
I have to perform this same test but outside of the building is all concrete, a shower room will be built in the basement but first the neutral to earth voltage needs to be tested, so how would I go about this?
Check with normal clamp or multimeter in volts mode between earth and neutral of any 3 pin socket connected to that service. The voltage value should be below 2. Hope this helps.

Great You from Kyoritsu Company Right
Thank you Sir this video very useful for all Electrical engineers
should be disconnecting earth cable from house to ground chamber first. so you will get the purest ground resistance.
Hiiii...
You mean, first disconnect the earth cable from earth pit??
OR
Can we shutdown the entire system before measuring earth resistance??
Pls guide
Disconnect the earth cable.
Of course he must have done that before starting the test otherwise the resistances of home equipment will distort the result
Mudah untuk difahami... Lama mencari video earthing test untuk menambah ilmu. Terima kasih boss

Please could you explain the operation of the meter and the readings.
Keep up the good work
One more thing what's the distance between two consecutive Earth Pit
what's the exact standard if you can please explain this the the minimum distance between two consecutive Earth pits
To individually test the earth rod disconnect tape from earth rod
Below 5ohm is acceptable right?
Yes

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)
Jika persekitaran rumah tamn agak sukar nk ambil bacaan,sb permukaan tanah @ berturap simen Dan jalan tar.

Shifting potential spike towards right and left is wrong.
Can i know whether before the individual earth rod being tested you have to remove the connection of the earth rod from the rest.
I am also have same question.

Shifting potential spike towards right and left is wrong.
What readings should tell me that the resistance is not okay please
depend on local regulation ..as lower as possible. .below 10ohm
if we had no access to such equipment will adding more grounding rods to the ground all connected together potentially reduce the earth resistance?
Yes.

I had an exams question in college how to do earth rod test . I didn’t pass it 😢
Saya nak tanya, bukankah testing dibuat semasa pemasangan rod sahaja (sebelum kita sambungkan dengan earth DB atau sebelum sambung ke perlindungan kilat)
Kedua2 nya boleh ..sebelum dan selepas ..Sebenarnya Cooper tape itu bukan utk pelindung kilat..
Your value of 1.63 ohms is a little high. Ideally less than 1 ohm is what you want...
Hello Sir,what if the result is above 10,let say 50..how can you improve this to 5?
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!
add more earthing rods all around the place the more the better🐱👍🏿
All earth rod supplies these days are carbon steel with copper coating add to and go deeper using brass connection.
music is shocking
hi sir. how do you perform it in a building where there is no earth ground to put the spike?
Extent green wire..
For condo there should have main electrical grounding
Test ini apakah harus saat listrik off?
I think 1/RT = 1/R1 + 1/R2 + 1/R3
Sorry your Appying the wrong formula, it's average, not resistances in paralel
thanks :)
Shifting potential spike in perpendicular ( left and right)direction is not correct.
The green wire is for?
electrode wire..
green wire is for grass. grass is green. make sense right? put green wire on grass and see resistance of grass. grass is green, green wire is green too. make sense right? right.
Hi Rictor , may i know how to know the result is good or bad? Many Thanks
low in reading is the batter .must below 10ohm.some time we can get 0 ohm. that the best..
It depends on your country standards. But the Best is the nearest to 0 ohms which is imposible to get 0 ohms. Also there are many methods to make the measurraments, it depends on your country standards too.

Much too long. Can't stand the music. Should begin with the schematic drawings.
Music is beautiful. If you don’t like the sound, turn the volume down! What an inappropriate comment!
The test should be done preferably during the driest season to prevent moisture from ruinning your values!

Apakah bisa di test dgn ohm meter tersebut
Kedalam nya sehingga rod gak bisa masuk lagi..baru di uji..jika masih tidak mendapat kan bacaan yg dikehendaki..buat point baru sehingga mendapat bacaan yg paling rendah
May i know why the cable for current is longer than the voltage?
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.
What about the grounding rod resistance?each rod shall be tested and removed all connected cable before the test of total resistance grounding.
