Earth Resistance Measurement

[@prasnthvarma9253]

Good job sir

[@belaoram5994]

Thanks sir.. explanation is good

[@sureshmt2467]

Nice explain

[@harishpoola4286]

Good explanations sir

[@vmohankumar7528]

Thanks sir 🙏🙏🙏

[@karthik.r1981]

Super sir

[@janardanbagkar5153]

Thanks sir .

[@kaleeswaranarumugam6658]

Thank u sir.

What the earth resistance value should be... Its less than3 ohm

[@ProtonSapien]

Excuse me Raja Sir, a doubt, Although you're fixed the electrodes equidistantly, why the value of resistance keeps oscillating? Whether we are able to arrive at a stationary point there? I couldn't make out it.

[@30mAkills]

Incorrect method.

[@sandranagamuneiah8142]

Thanks sir

[@sheesh1706]

Why did you short E1 and P1?

[@30mAkills]

4 pole meter is for measuring soil resistivity which is different subject. For testing earth pit resistance, we have to convert it to 3 pole by jumpering or linking P1 and C1.

[@sheesh1706]

​@@30mAkillsCan you recommend some reading matter on the subject

[@tsivaramakrishna8941]

Sir what is the diameter of the two electrodes

[@30mAkills]

Diameter and depth of spikes are not that important. Can use 8 mm steel rod of about 200 mm long like screwdriver.

[@solastygunplay]

I need it please

[@nasruddinsiraj4083]

It's not stops eat right.....

[@30mAkills]

Incorrect method

[@rajutitanium417]

In that meter, one is 10 ohm and 100 ohm what does it mean

[@30mAkills]

Range in ohms.

[@rajutitanium417]

This reading 13 & 16 having any unit

[@30mAkills]

Ohms.

[@soubhagyanaik4414]

Sorry Sir, kindly speak Slowly and Clearly english language. Why reading is always variable

[@30mAkills]

Sorry uploader. Your method is absolutely incorrect as the spike spacings are not as per Fall of potential method. You didn't mention the depth of the earth electrode under test. You didn't tell whether the earthing system is energized or not. You didn't mention the ideal resistance value. Shows you don't have practical knowledge. Earthing is done for safety reasons. Don't please misguide. That log book tabulation is wrong. 35 k views and nobody has pointed out the mistakes because they don't know. We real testers won't reveal the proper method. This is the reason that nobody (domestic and commercial services) check their earth pit resistance value. You didn't tell about RCCB and TT earthing system.
