Earthing is done to connect the non-current carrying parts of the electrical apparatus to the general mass of earth in such a manner that all times an immediate discharge of electrical energy takes place without danger. A good earthing system would ensure the following:
- Protect users from danger of electrical shock by blowing a fuse
- Ensure that the conductive parts of an electrical equipment does not reach dangerous potential
- Provides a safe conducting path that successfully dissipates short circuit currents
- Preserves the voltage at any part of an electrical system at a known value to avoid passing of excessive current or voltage on the appliances or equipment
Earthing provides protection against static electricity from friction
Earthing is paramount in saving lives of people and mitigating vulnerabilities to sensitive electrical equipment. Earthing strips are employed to divert the fault current through an alternative route to the ground so as to safeguard the equipment.
What to look for in a good earthing strip?
The earthing strip should exhibit low resistance to electrical current, should be able to withstand the impact of corrosion inducing agents and must be capable of dissipating abnormal fault current regularly.
The strips should be constructed out of superior quality copper, aluminium or Galvanized Iron (GI). Flexibility in thickness and width should be present. A normal earthing strip may have its thickness anywhere between 3 to 6 mm whereas the width may vary from 15 -100 mm. This flexibility ensures that the strip can prove useful in varied applications. The thermal and electrical conductivity of the earthing strip should be good. Galvanized strips come loaded with all the qualities that you may seek in a perfect earthing strip. Disregard of safety matters and use of faulty electrical equipment have claimed many lives. Hence the earthing strip you choose for your application should have accurate dimension, robust build and corrosion resistance.
Galvanized earthing strips are manufactured using premium quality iron or steel. The strips are subject to galvanization in accordance with the ISI specifications. Earthing strips are most preferred in areas where the soil conditions are rocky. The coating of zinc on the galvanized strips is recommended to be a minimum of 80 microns. The hot dipped galvanized iron strips have a width in the range of 25-75 mm and thickness of 3-12 mm. The strips have protracted life and require very little maintenance during their lifetime.
