Compiled on: Mar 13 2001 Copyright: Ground-it.com Consulting Ltd. -------------------------------------------------------------- * FILE: SAMPLE2.KDA * Created on March 12, 2001 by Ian Simpson * Example of a 19 x 20 m ground grid with rods and angled conductors in * two layered soil * Calculation of fall-of-potential curve * Perimeter conductors * These are entered using the intelligent format * Injected current * Other conductors * These are entered using the basic x,y,z format * rods * The next electrode is the fall-of-potential return electrode * Returning current * Fall-of-potential profile Upper layer resistivity: 47.0000 ohm-meters, depth: 1.3000 meters Deep layer resistivity: 28.0000 ohm-meters. Calculation accuracy selected: 0.001000 used: 0.001000 METRIC units of measure.
