WORLD'S MOST POWERFUL TRANSMISSION LINE
December 4, 1946
Sharon, Pa., Dec. 7 -- Three transformers, built to step-up electric current to as much as 500,000 volts -- nearly 75 per cent greater voltage than that now carried by any transmission line -- are shown in the test pit of Westinghouse Electric Corporation's Transformer Division here.
The transformers, each 37 feet high and with extra heavy insulation to withstand the as-yet-untried transmission voltages, are being built for the American Gas & Electric Service Corporation's experimental line near Brilliant, Ohio.
The A. G. & E. test seeks to determine the feasibility of transmitting electric power longer distances at greater voltages than ever before attempted.
A 287,000 volt line, the highest voltage line now in existence, can transmit power approximately 250 miles.
