Title Calculation of earthing plates for electrical systems in mines and quarries
Original title K rasčetu zaščitnyh zazemlenij šahtnyh i kar'ernyh ėlektroustanovok [in Russian]
Bibliographic information Dec. 1973, No.12, p.63-66. Illus. 4 ref.
Abstract In view of the difficulty of efficiently earthing mine and quarry electrical systems owing to the high resistivity of most of the minerals mined, equations were derived for determining separately the conductivity of phase earth connections and earth circuits. The continuity of the earthing system plays a decisive part.
