FIELD: electricity.
SUBSTANCE: method of measurement of resistance to current spreading, according to the invention, lies in the installation of the auxiliary potential electrode made of a material that provides the maximum external contact potential difference in relation to the ground. The external contact potential difference is determined using voltmeter with high internal resistance. The grounding and auxiliary potential electrode are connected through the high resistance load resistor and ammeter connected serially. The current flowing through load resistor is measured. Resistance to current spreading is calculated using Ohm's law for the complete chain.
EFFECT: reduction of the complexity and cost of measuring the current spreading resistance.
