With a view to the deficiency of grounding resistance measurement at present, a new method with short current-electrode wire based on computer auxiliary analysis is presented.
It is a rather good auxiliary material with good resistance to oxidation at high temperatures and electrochemical corrosion and with no deformation when operating at high temperatures.
