What is Grounding Enhancement Material Comparison about?

This study evaluates the effectiveness of various grounding enhancement materials (GEM) in reducing earthing resistance for electrical systems. Sodium Chloride and Copper II Sulphate significantly lower earthing resistance by over 85%, but the commercial GEM demonstrates superior stability and moisture retention over time. The findings highlight the need for periodic replenishment of salt-based materials due to their susceptibility to dissolution from heavy rainfall.
