Insulation of High Voltages.


A dispatch from Marysville, Cal., to the San Francisco Chronicle, dated May 13th says: "An experiment concluded here by Dr. F. A. C. Perine of Stanford University for utilizing the electric power line of the Yuba Power company from its power house to Brown's Valley, a distance of 10 miles, has resulted in demonstrating that 36,000 volts may be transmitted over a copper wire using glass insulation, against 16,000, which has been the maximum in practice in power transmission heretofore. The result of the experiment will be to effect a saving of half the cost of wire in the construction of electrical-transmission plants in future. As it is now, the cost of wire is about half the entire cost of a plant. The exact loss in the transmission of this high current has not as yet been made known."
