Earthing of Telecommunication Installations

image of Earthing of Telecommunication Installations

A great deal of research has been done on earthing problems in connection with telecommunications and several technical papers have been published as a result. Although opinions and practices differ, there is also a large measure of unanimity on certain aspects. This first edition of a handbook on earthing is an attempt to set out those principles on which a measure of agreement has been reached, and, in those cases where there are different possibilities, to compare their merits.



Earth electrodes

The major factor involved in establishing an earth electrode system is the soil resistivity in the region concerned. Soil resistivity is largely dependent on factors which extend over large areas, but local variations may indicate particular points favourable for the establishment of earth electrode systems giving advantageous values of earth resistance.
