RESEARCH INTO ACTION OF SURFACE SOIL MOISTENING, DRYING OR FREEZING ON ELECTRICAL CHARACTERISTICS OF GROUNDING DEVICE
Journal Title: Електротехніка і Електромеханіка - Year 2014, Vol 0, Issue 1
Abstract
The analysis made has shown expediency of modernization rather than reconstruction of earth electrodes, after inspection of long operating substations grounding grids, via building a two-level structure. It will result in both technical and economic effects. The novelty of the results consists in studying, by means of a mathematical model, electrical characteristics of a two-level earth electrode versus the depth of surface soil drying or freezing.
