LIGHTNING ON A TANTRUM
August 22 & 27, 1938
Running amuck, this artificial lightning stroke broke out of its prescribed path, leaped through the air and cut a zig-zag path down the partition which protected the lightning investigator in the Westinghouse high voltage laboratory at Sharon, Pa.
The engineer stood within two feet of the man-made bolt which carried 50,000 amperes of current at a pressure of more than 3,000,000 volts. Only a fraction of the lightning stroke remained in the transmission pole.
