EARTH GROUND SYSTEM DESIGN AND EVALUATION

Model K2-10 ground rods were installed, tested, and evaluated with copper-clad steel (CCS) and CCS salt-enhanced (CCSS) rods at field sites and the National Aviation Facilities Experimental Center (NAFEC) for comparison and determination if they meet the manufacturer's specifications in high-, medium-, and low-resistivity soils under arid and wet conditions through a year of seasonal change. It was determined at most sites that the XIT-rod-to-earth impedance remained lower than the CCS and CCSS rods under the above conditions, although seasonal impedance variations did exist. XIT rod earth impedance remained well above 4 ohms at most sites. XIT rod installation costs were greater, and unit costs were much greater than CCS and CCSS rods. The engineering approach used herein may be a useful guide for engineering ground systems at field facilities. (Author)
