Revision Standard - Active. The measurement of thermal resistivity of soil and backfill materials to include concrete, engineered backfills, grout, rock, sand, and any other material used to encase the cable system installed in the ground is covered in this guide. A thorough knowledge of the thermal properties of a soil or backfill material enables the user to properly design, rate, and load. This guide covers the measurement of soil thermal resistivity. A thorough knowledge of the thermal properties of a soil will enable the user to properly install and load underground cables. The method used is based on the theory that the rate of temperature rise of a line heat source is dependent upon the thermal constants of the medium in which it is placed. IEEE Guide for Soil Thermal Resistivity Measurements A method for measurement of soil thermal resistivity that is based on the theory that the rate of temperature rise of a line heat source is dependent upon the thermal constants of the medium in which it is placed is given. May 21,  · Abstract: One of the most important factors affecting underground cable ampacity is the thermal resistivity of the soil. It is well known that thermal resistivity of the soil will vary with moisture content. It is also well known that the heat generated by cables can cause soil drying thus affecting the soil thermal resistivity. The ability of the soil to maintain its thermal resistivity in the presence of a heat source is known as thermal kauainenehcp.com by:

Dec 28,  · Purpose: The purpose of this guide is to present practical instrumentation methods that may be used for measuring soil resistivity, the impedance to remote earth, step and touch voltages, and current distributions in ground grids associated with electric utility facilities. These grids typically consist of interconnected grounding systems ranging in complexity from a few ground rods to large grids with many ground rods or wells, buried conductors, and external ground connections. May 23,  · Abstract: The thermal resistivity of the soil surrounding a power cable is a very important factor in evaluating the load-carrying capability of underground cable.
