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

in that situation ..yes..

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

I am also have same question.

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.

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

Yes.

@@rictorrictor888 🐱👍🏿

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.

It means your earth grounding is perfect, anything less than 5ohm always consider perfect earthing as per indian standard 🙂

It's over limit. U need to dial up the limit. Cannot use 20ohm. Because the reading is above 20 ohm

How about if the reading is 25ohms What can i do to get less than 5Ohms?

@@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.

@@30mAkills Thanks🙏🙏

Tqvm

you silly person. what sort of system are you on?

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.

@@frankkennedy7831 Perhaps you are the silly person making such an inappropriate comment! 🤢

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.

Extent green wire..

For condo there should have main electrical grounding

Shifting potential spike towards right and left is wrong.

thank you so much

Shifting potential spike towards right and left is wrong.

Yes..same.

For soil testing and also in hill areas.

kalau kawasan tar @ bersimen, boleh guna metal screen @ earthing mat. letak pada jarak yg ditetapkan & siram dgn air jd blh buat measurement

depend on local regulation ..as lower as possible. .below 10ohm

Kedua2 nya boleh ..sebelum dan selepas ..Sebenarnya Cooper tape itu bukan utk pelindung kilat..

0 ohm

@@rictorrictor888 Practically not possible. Is earth full of gold?

@@rictorrictor888 I wish 😂

5 meters up to 10 meters it depends on soil type

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.

@@30mAkills Thank you for this comment - can you please provide some formal references to confirm y you our comment - Thank you!

Yes

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.

Shifting potential spike in perpendicular ( left and right)direction is not correct.

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.

Total of test 1 ,2 ,3 then / by 3..it show on video min 13.20

dasarkan 20ohm setting

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

@@File-Transfer I don't know about that

Good ..under 10 ohm

Thanks sir......

Ya udah juga..terima kasih..

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.

yes..

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

show me photo..

The valor is over the Range selectionated in the istrument or the cables are not conected correctly to the Spikes You should to check again all the conections. If the problem continue changue the Spikes of place.

@@octaviohurtado2779 Thank you! I'll check carefully. Good day!

@@rictorrictor888 Sorry, I don't know how to share a photo via a youtube comment. Anyway, I'll check my device. Thank you for your guidance.

Find another location for grounding the rod..

De-energize that service and procced if the voltage is more than 10.

He worries falling mango fruit..hahaha

@@rictorrictor888 hahahaha ;-)

there are flying cats around in the neighborhood

tetap kena dapat kan bacaan bawah 10 ohm juga...tapi ada kaedah2 untuk menurunkan bacaan jika di buat atas tanah berbukit..tq

Sa lbih 15ohm bgtu

Nnti whatapps kmi 0138724857 mhu tnya kaedah lain

@@bruce.bchannel9046 boleh tambah point lagi tu..atau guna wayer tembaga bogel gulung jadi kan coil...tanam terus dlm tanah.hujung nya sambung ke electrod yang sedia ada..

Mcm mna cara ti

break concrete and place into the soil below?

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.

@@fje1948 planet Kittygystan 🐱 of the 23rd Constellation, why do you ask amigo?

Sorry your Appying the wrong formula, it's average, not resistances in paralel

Protect human and electrical equipment from electric short

Maybe the humidity in UK is different if we compare to Malaysia. The water in soil can effect the meter reading.

@@azleeman biasanya ada 2 jenis earth tester yg selalu diguna measure grounding resistance. yg dlm video ni guna kyoritsu & location potential spike tu ditengah2 antara ground rod & current spike. yg satu lg jenama megger tapi jarak potential spike tu 62% dari jarak antara earth rod & current spike. & potential spike tu kena ubah 10% ke depan % 10% ke belakang dari kedudukan asal & diambil average dr 3 reading td. mungkin kat uk guna jenama megger sbb tu dia ckp different dgn kt sini.

All over the world FOP (Fall of Potential) method is same.

Incorrect@@30mAkills

@@johnhayhurst5884 then tell the correct. Here our earthing is TT.

kita uji dahulu jika terdapat voltage dalam tanah.. terutamanya di kawasan kediaman yang berdekatan dengan sub station

kalau ada voltage baguslah pasang diode boleh charge bateri kereta anda🐱👍🏿

Hahaha..Mr bean vers 2

The results would only be resistance on the load , not main earth resistance

@@Godfa539 will you justify this statement please?

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.

More accurate ..

And if you need to get only one value, measure twice to rule out reading errors.
