“…Stainless steel was used by the former Soviet Union as a grounding conductor. Due to the chromium element in stainless steel, the electrode potential of steel changes from negative to positive, which gives it a good soil corrosion resistance [ 42 , 43 ]. However, in soils with poor air permeability, stainless steel is extremely prone to pitting corrosion.…”

A grounding grid plays the role of discharging current and balancing voltage to ensure the safety of the power system. However, soil corrosion can damage the grounding grid, which then can endanger the safe operation of power system. This paper reviewed recent research advances of soil corrosion of grounding grid. The cause, mechanism, types, and influencing factors of soil corrosion of grounding grids were summarized, and the corresponding detection technology and protective measures were also introduced. The paper pointed out that soil corrosion is a serious threat to the grounding grid system. Moreover, the impact mechanism of AC stray current, new corrosion detection technology, and better protective measures still need in-depth research.

“…Therefore, corrosion prevention to metal buried in soil is important. At present, research surrounding buried metal corrosion mainly focuses on (1) factors affecting corrosion to buried metal 25 ; (2) metal-protection methods 26 27 ; (3) methods of judging the metal corrosion degree 28 ; and (4) corrosion of metal in different media 29 . However, all of the soils from the study are natural and have undergone sufficient soil-forming processes.…”

Taking the slope of Suiyu Railway to study, the research separately studied soil resistivity, soil electrochemistry (corrosion potential, oxidization reduction potential, electric potential gradient and pH), soil anions (total soluble salt, Cl−, SO42− and ), and soil nutrition (moisture content, organic matter, total nitrogen, alkali-hydrolysable nitrogen, available phosphorus, and available potassium) at different slope levels, and conducted corrosion grade evaluation on artificial soil according to its single index and comprehensive indexes. Compared with other factors, water has the biggest impact on the corrosion of slope protection net, followed by anion content. Total soluble salt has the moderate impact on the corrosion of slope protection net, and stray current has the moderate impact on the corrosion of mid-slope protection net. Comprehensive evaluation on the corrosive degree of soil samples indicates that the corrosion of upper slope is moderate, and the corrosion of mid-slope and lower slope is strong. Organic matter in soil is remarkably relevant to electric potential gradient. Available nitrogen, available potassium and available phosphorus are remarkably relevant to anions. The distribution of soil nutrient is indirectly relevant to slope type.
