How an Explosion (Not Aliens) Turned New York’s Night Sky an Electric Blue
The bizarre illumination was sparked by an “electric arc flash” tied to faulty equipment at a Con Edison substation, a spokesman for the utility, Bob McGee, said early Friday.
A voltage detector at the substation failed, which led to the electrical fault that caused the arc, Con Ed’s chairman, John McAvoy, said at a news conference Friday.
The fault went on for longer than would normally be expected, he added, because a protective device did not work as quickly as it normally would.
