DETERMINATION OF THE SOIL CONDUCTIVITY AND RESISTIVITY IN OLOGBO, EDO STATE FOR THE SUITABILITY OF TRANSMISSION CABLE.

Soil thermal resistivity or conductivity testing, measures the capability of the ground to conduct or dissipate heat away from the immediate surroundings of a pipeline or a transmission cable. In this article, thermal resistivity/conductivity measurement was carried out at the ELPS CS1 site at Ologbo Edo State, using a Terameter (SAS 1000). The measurements were carried out by strictly adhering to the IEEE 442 and ASTM Guide standard for soil thermal resistivity/conductivity measurement. Thermal resistivity values measured at the various points along the entire test sites shows range of thermal resistivity values is between 0.3966( oC m/W) to 0.5961( oC m/W), while the range for thermal conductivity which is an inverse of thermal resistivity is between 2.5214 (W/oC m) to 1.6775 (W/oC m) correspondingly. The values are within the safe limit of 0.9000oC m/W standard, specified for buried underground facilities.
