Description
Summary:This study shows that there is a need to improving ac power supply grounding systems with the help of reinforced-concrete supports and foundations as natural ground sources. An equivalent circuit for wet concrete is presented that takes into account the transverse filling of air pores. The dependence of the specific resistivity of the catenary system’s reinforced concrete pores and foundations on the structural moisture and temperature is shown. The moisture relation of electrical breakdown voltage is calculated for the catenary system’s reinforced-concrete supports and foundations.
