HIGHEST VOLTAGE TRANSFORMER
December 8, 1960
PITTSFIELD, Mass., December 8 -- World's highest voltage power transformer, left of concrete wall, steps up incoming voltage to a range of 460,000 to new world high of 750,000 volts at General Electric's Project EHV (Extra-High-Voltage) near here.
Regulating transformer, at right, regulates the 115,000-volt incoming supply by +30 percent to allow different voltages to be tested on the line.
Probably the world's largest bushings extend 18 feet above and 10 feet into the power transformer.
