Artificial Lightning

June 1938

Here's what happens to a transmission pole when lightning strikes it.

Used in a test of man-made lightning at the Westinghouse high voltage laboratory in Sharon, Pa., this pole was submitted to a stroke of 50,000 amperes at an applied voltage rise of between three and four million volts.

This combination of steep voltage and high current is comparable in effect to natural lightning.
