ELECTRICAL GROUND CONSTANTS OF CENTRAL, EASTERN, AND NORTHEASTERN THAILAND

Abstract

Two methods suitable for measuring electrical ground constants in Thailand are described. The ground conductivity was measured at the broadcast frequencies of 820 kHz and 1455 kHz using the field-attenuation method. The ground dielectric constant was measured by the wave-tilt method at the high frequency of 27 MHz. Details are given for constructing the necessary equipment, and procedures for the collection and analysis of the data are outlined. The ground conductivity and ground dielectric constants in central, eastern, and northeastern Thailand were measured. The report also contains recommendations for improvements in equipment and measurement procedures. (Author)
