Аналіз можливості застосування існуючих приладів зондування ґрунту в рамках діагностики стану заземлювального пристрою

Abstract

Based on the developed methodology and the statistical database of the specific electrical resistance of the soil, the technical characteristics of the most commonly the measurement equipment used in vertical electrical sounding in the test of the state of the grounding grids were investigated. By means of confidence probability recommendations worked out on application of equipment with corresponding parameters, depending on the voltage class of energy object. Also it proved the necessity to develop a domestic the measurement equipment for vertical electrical sounding on the place of power plants with 35-750 kV voltage class.
