HIGH-TENSION SWITCHING In the matter of protection against damage by fire or againstliability of accident to employees, it would be hard to find aplant using high-tension current for operating motor-generatoror rotary-converter sets for direct-current distribution in whichgreater precautions have been taken than are displayed in thedesign of the North Shore power station. The entire electricalengineering of the station has been performed by A. H. Bab-cock, electrical engineer of the North Shore Railroad Company,and the results of his experience, gained during his connectionwith the leading transmission companies in California, havebeen well applied in this station. The main idea sought, as maybe inferred from the fo
