PROTECTION FROM LIGHTNING

Artificial Lightning

June 1947

WHEN LIGHTNING STRIKES, a power line may be put out of commission, so engineers make their own lightning, to learn how to control it.

Here, in a Westinghouse laboratory, an artificial stroke of nearly four million volts is hurled at a distribution transformer. Protective devices bypass the lightning to the ground and there is no interruption of service.
