Abstract

4353. Geppert, H. Feb. 22. Protective arrangements.-Metallic articles, such as pipes, cables, &c., embedded in the ground near live conductors, are protected from earth currents by connecting them to the negative pole of an auxiliary source and embedding anodes connected to the same source. A pipe b is shown connected to the negative pole of a source f, and various conductors d, preferably interchangeable and made of carbon, nickel, platinum, gold, &c., are connected to the positive pole of the source f. A current thus flows through the earth to the pipe b, and prevents electrolysis by any leakage current from the tram rails a. Resistance may be included in the protective circuit, and its electromotive force may be supplied by the source i in the main circuit, instead of by the source f. The anodes d may be surrounded with damp clay or earth saturated with brine. If the conductor e is not insulated, it may serve as an anode ; if it is insulated and sheathed, the sheath may be connected to the negative pole of the source f. This system may be employed to protect iron standards.
