Artificial Lightning

no date

Forty-seven capacitors or storehouses of electric charges in this 4,900-cubic-foot surge generator produce segments of real lightning with which to test all completely self-protected distribution transformers made by the Westinghouse Electric & Manufacturing Company at Sharon, Pa.

Thirty-two capacitors in the bottom section are capable of developing 100,000 amperes, while the upper bank of capacitors produce a steep lightning wave front of 1,500,000 volts per millionth of a second.
