New York Blackout Relay Protection

New York Blackout Relay Protection

On the evening of July 13, 1977, New York City lost power not because of a single failure, but because a protection system designed to isolate faults instead isolated the city itself. A failure of the substation's relay protection system has caused the Manhattan blackout in New York City, the Con Edison energy company said in a statement on Monday. Dvorkin is a professor in the department of electrical and computer engineering at NYU Tandon. UPDATE: July 30, 2019: Consolidated Edison announced on Monday its conclusion that the July 13 blackout was caused by a "flawed connection between some of the sensors and protective relays at the substation. " The utility company said the faulty system was at its West 65th Street substation. New York Mayor Bill de Blasio, center left, listens to Con Ed President Tim Cawley, July 14, 2019, as the mayor visits the site of the power outage on July 13, on New York's Upper West Side.

New Type of Earthquake-Resistant Cabinet

New Type of Earthquake-Resistant Cabinet

Seismic cabinets are engineered with reinforced structures to stay stable and protect equipment during intense motion. Protection extends beyond earthquakes to vibrations from railways, machinery, and construction. The enclosures are loaded with simulated equipment and placed on a shaker table designed to replicate the force of an earthquake. Matt Springer has been giving presentations around San Francisco about home earthquake preparedness since 2008 (for more information about the presentation, go to his earthquake preparedness website).
