Earthing Electrode

Earthing Electrode is the component of the earthing system, which is indirectly connected to the ground and provides a path for leakage current. In the earthing system, a quite large number of electric current is required to carry fault current for a short period. The most preferred material is copper and galvanized steel. Sometimes, aluminum is used for above ground “bonding,” but most of the standards forbid its use as an earth electrode, due to the risk of accelerated corrosion. The corrosive product is a non-conductive oxide layer, so it may reduce the effectiveness of the earthing.

Renown Earth is engaged in the manufacture and supply of a wide range of chemical earthing electrodes to our clients and manufactures a wide range of raw materials keeping in mind our customer’s requirements and demands. We have a huge demand for our Chemical Earthing Electrode.

A GI chemical earthing electrode contains the following features:

  • Strip in channel technology.
  • Galvanised iron pipes are used.
  • A highly conductive material is dripped inside the electrode to prevent corrosion and to reduce resistance.
  • The weight of a 40 mm diameter electrode is as per industry standards and likewise for other diameters.
  • Earth enhancement material is used especially in areas of poor earth conductivity.
  • Earth enhancement compound (or backfill compound) has NABL Lab tested 0.039 Ohm-m resistivity.
  • The fast fault current dissipation is smooth.
  • The electrode is favorable for all conditions of the soil.
  • A custom-made G.I. tube with adequate galvanization is used in this electrode.
  • The fluctuation of the Ohmic value is the least.

Backfill Compound

Backfill helps absorb moisture around the electrode which should be non-corrosive and should be of relatively small size if possible. The dug soil is suitable for backfilling compounds if large stones are sieved and placed around the electrode. The pH value of the solid should be between 6.0 acidic and 10.0 alkaline. Stiffed clay is not suitable for back filler material as it is heavily compacted.

It is thermally stable between -100 degrees Celcius to +600 degrees Celcius. It is highly non-corrosive in nature but highly hygroscopic. Furthermore, it has low water solubility.

Method of Electrical Earthing

The common method of electrical earthing is the GI Chemical Earthing Electrode. This pipe is located inside the earth. After it, a layer of sand salt charcoal, and ground enhancement material covers the electrode.

There is a funnel on the top of the pipe electrode for the watering purpose to moisturize the electrode. As moisture is very necessary for any type of earthing system.

When the water poured through the funnel at the top of the earthing electrode, water is spread out through the hole thus closing the surrounding salt charcoal. The result is that water starts to rust the pipe and breaks the pipe within 2 or 3 years. Hence, the purpose of earthing fails.

As we know water and salt are used to reduce soil resistivity and low resistivity is good for earthing purposes, but low resistivity causes the most corrosion effect.
