For earthing pipe of 40mm dai & 3 mtr. Long required 5 kg. Of salt & 6.5 kg of charcoal. This type of earthing is done for distribution transformers of various rating.
Salt is not a good conductor of electricity, but salt solution is a good conductor. Salt maintains moisture and charcoal gives good conductivity causes earth point/pit in good electrical conductivity place
Salt to dissolve in the soil moisture to serve as the conducting electrolyte. It will exhaust more rapidly in rainy season and will need replenishment. Charcoal to dissipate the heat generated (IxIxRxt calories) when the lightning current is discharged into the earth. It will eventually burn up into ash and need replenishment.
No. You will need to distill the water to do that.
I want to use bentonite powder in place of salt and char coal for earthing of distribution Transformers and electrical lines
We use earth pits for by-passing the high voltages from the lightning rod in case of thunder strikes.. After digging earth pits, salt(na-cl) & charcoal.....salt increases conductivity, whereas charcoal decreases conductivity......so we use charcoal
Goldfish don't need salt because they are Freshwater Fish!
put this mixture in water. salt will dissolve in water. now filter this solution with a filter paper. we will get particles of charcoal on the filter paper as residue. now heat the solution of salt and water .the water will evaporate leaving behind salt. thus the mixture of charcoal and salt is separated.
Depending on the needed concentration of salt !
yes you need salt to live. but you don't want to much or you can be really sick.
The conventional earth is the use of a copper rod and plate driven into the earth.In dry areas this may be not sufficient to make a good earth and chemical systems are available. Chemical earths use a more resistant material to copper in the form of a tube packed with chemicals.These earths are more for the use of lightning conduction rather than electrical safety earth.Very popular in India.
you need just 3 pinch of salt!!
