What is the use of red and yellow wire

[@electricalvathiyar1753]

இந்த கருவி Earth resistance அளவீட்டை fall-off potential முறையுடன் செய்கிறது, இது அளவீட்டு பொருள் E (எர்த் எலக்ட்ரோடு) மற்றும் C (C-Red wire spike) (தற்போதைய எலக்ட்ரோடு) இடையே ஏசி கான்ஸ்டன்ட் கரண்ட் I ஐப் பயன்படுத்துவதன் மூலம் Earth resistance மதிப்பைப் பெறுவதற்கான ஒரு முறையாகும். E மற்றும் P (p- yellow wire spike) (சாத்தியமான மின்முனை) இடையே உள்ள வேறுபாடு V.
Rx = V / I
This instrument makes earth resistance measurement with fall-of potential method, which is a method to obtain earth resistance value Rx by applying AC constant current I between the measurement object E (earth electrode) and C (C-red wire spike)(current electrode), and finding out the potential difference V between E and P (p-yellow wire spike) (potential electrode).
Rx = V / I

Sir why connect from earth yellow 5mtr,red 15mtr,

[@electricalvathiyar1753]

Yellow shall be 5 to 10 mtrs, not less than 5 metres.
Three readings should be taken by changing the yellow wire spike to 5m, 6m and 10m.
The red spike shall be 10m away from the yellow spike.
The average value is the final value.

[@30mAkills]

@@electricalvathiyar1753 as per fall of potential or 62 % method if current spike red is placed @15M then potential spike yellow has to inserted @ following distances from earth pit as zero reference point:
1) 7.8m (52% of 15m)
2) 9.3m (62%)
3) 10.8m (72%)
Also you didn't check the lead wire resistance.

Good morning sir
Sir please explain
No 1 from earth pit to yellow wire how many meters
No 2 from earth pit to red wire how many meters
No 3 minimum excepts below ohms ?
Thank you 🙏

[@electricalvathiyar1753]

1. Yellow wire 5 metre from earth pit
2 Red wire 15 metre from earth pit
3. Less than 20 ohm is ok but Authority recommendation will be less than 10 Ohm
So, maintain always less than 10 Ohm.

[@30mAkills]

Please go thru my reply to another commentor regarding the same doubt.
The uploaders answer is not correct.
