An Efficient Method for Earth Resistance Reduction Using the Dead Sea Water

摘要

To protect humans, devices and maintain high reliability of electrical equipments, efficient earthing system has to be provided for residential and commercial buildings. The use of chemical elements around the electrode of earthing systems reduces the earth resistance which improves the efficiency of these systems. However, the use of these elements can't achieve very small earth resistance especially in the case of dry clay. In addition, they are expensive and not available all the time. This paper presents a method that treats the soil with adding the Dead Sea water instead of the chemical elements to further reduce the earth resistance and to avoid the expenses of these elements. In our approach, the Dead Sea water is added to a hole around the electrode with a distance not exceeding 10 cm to avoid the corrosion layer on the electrode. Practical measurements are demonstrated to show the efficiency of the proposed approach.
