| Abstract: | This paper studied on the electrochemical measurement methods of substation grounding grids＇ corrosion, using a practical grounding grid corrosion detection device that places the Cu/CuS04 reference electrode and graphite auxiliary electrode in the insulated cavity to constitute a three-electrode system with carbon steel working electrode, and using the CMB-2510A corrosion rate meter to measure the polarization resistance of grounded metal in situ,the homemade simple current limiting probes can limit the area to about 2.5 cm^2 , so it can effectively determine the corrosion status of grounding grid without excavation. |
