Excerpt from A Compressed Air Switch: ThesisThe power in electric circuits, however, has increased very rapidly. With very severe arcs gases were formed in the 011. These gases expanded and caused the oil to be thrown out of the Openings in the casing, or if there were no Openings the casing might be blown to pieces. The ordinary single cell oil switches were not used to break power exceeding 5900 kilowatts. No oil switch.was warranted to break power of more than 40000 kilowatts. These sizes, however, were sufficient until quite recently, but in some stations this safe allowable load for the switch has been exceeded. In this case the power is sectionalized, that is, divided up so that no one feeder in a generating station may carry over 40000 kilowatts.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
