FIELD: measuring equipment engineering, in particular, engineering of equipment for measuring specific electric resistance of grounding devices. ^ SUBSTANCE: to achieve result, current electrode is made in form of screw with driving abutment thread, directed towards its immersion into soil, and is provided with supporting plate for operators, on which guiding nut is vertically held, made of dielectric material with low friction coefficient. Also, there is internal abutment thread made on the nut, appropriate for thread on current electrode. ^ EFFECT: improved measurements precision. ^ 3 cl, 1 dwg |
