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.
The arming switch, S1, is connected with two short lengths ofwire to the two holes marked S1 in the component placement diagram below.

With the principle of measuring resistance, the paper carries through the theory analysis about possibility of measurement method with short electrode wire.
