  7. How to Decrease Earth Resistance? www.comcopak.com| 13-M Commercial DHA Lahore

  8. How to decrease earthresistance 20 feet TRENCH 10 Feet 10 Feet By increasing the area of the conductor in contact with the soil. BY increasing the length of the rod. By inserting parallel rods. By replacing soil with a low resistivity material (PES) By increasing the area of ground system. 10 Feet PES PES www.comcopak.com| 13-M Commercial DHA Lahore

  13. Importance of First Few Inches of Soil Around a Copper Rod • 6 to 8 inches around a copper rod contribute 52 % of earth resistance. Solution : Use of a low resistivity material in this area (PES) Recommendation: IEEE Std. 80-2000 6 to 8// Low Resistivity Material (PES) www.comcopak.com| 13-M Commercial DHA Lahore

  14. IEEE Std 80-2000 • It is often impossible to achieve the desired reduction in ground resistance by adding more grid conductors or ground rods. An alternate solution is to effectively increase the diameter of the electrode by modifying the soil surrounding the electrode. (Page 68) • The inner shell of soil closest to the electrode normally comprises the bulk of the electrode ground resistance to remote earth. This phenomenon is often utilized as advantage. (Page 68) • Ground enhancement materials, some with a resistivity of less than 0.12 Ω·m (about 5% of the resistivity of bentonite), are typically placed around the rod in an augured hole or around grounding conductors in a trench, in either a dry form or premixed in a slurry. Some of these enhancement materials are permanent and will not leach any chemicals into the ground. (Page 68) www.comcopak.com| 13-M Commercial DHA Lahore

  15. Features of PES • Physical Appearance Powder Form 200 – 250 mesh • Low Resistivity • High Conductivity • Permanent • Maintenance Free • Maintain Earth Resistance with time • Set Firmly, Does not dissolve or React • Does not pollute the Earth and Water Table • Suitable for Installation in Slurry Form • Does not Depend on Presence of Water • Perform in all Soils • Perform in all Weather Conditions • No Reaction with Electrode • Protect the Electrode & save Investments www.comcopak.com| 13-M Commercial DHA Lahore
