Why Are Salt & Charcoal Added in Earthling Pit??
Answer :
Coal or Charcoal is made of carbon which is good conductor which can minimize the earth resistance.
The salt is use as electrolyte to form conductivity between the earth electrode Coal and Earth with humidity.
Sand has been used to form porosity to cycle water and humidity around the mixture.
The main purpose of providing earthling is to discharge the leakage current or the fault current safely to the ground.
That Means better conductivity of the soil or lesser its resistance. So Adding charcoal and water in earthling pit which can decreases soil resistivity.
The layer of charcoal and salt helps to maintain low resistance path for earth fault currents.
Because of ionic behavior of the salt and charcoal they will be maintain moisture content all around the earth pit.
How much charcoal and salt is used in earthing?
31 ratio of charcoal & salt used in one earth pit for good result. Our charcoal is highly acclaimed in electrical uses that are used along with salt for earthing ,which gives a temporary solution for getting low resistivity.
What is the good earthing value?
Ideally a ground resistance should be of zero ohms. There is not one standard ground resistance. The NFPA and IEEE have advices that a ground resistance value of 5.0 ohms or less.
Which is the best earthing?
Plate earthing is the best earthing.
Which of the following is used in earth pit?
Salt and charcoal are added in the earth pit for improving conductivity.
How many kg of salt and charcoal is used in pipe earthing?
The amount of charcoal and salt needed for GI pipe earthing are 10 Kg and 10 Kg respectively.
So, due to this reason Salt & Charcoal Added in Earthing Pit.
