| Abstract: | Showed the feasibility of using steel electrodes to measure potential gradient caused by the stray current in soils.A special device with arranged steel electrodes and controlled interferential electric field in water pool was designed. The effects of direction, strength of interferential electric field, as well as the ananged space between steel electrodes on measured potential gradient were investigated. In addition, calculation formula of potential gradient was validated and the error caused by potential fluctuate of steel electrodes was also discussed. |
| Keywords: | corrosion induced by stray current in soils DC potential gradient measurement steel electrode experimental |
