Breaking New Ground: Digital Twin Helps Engineers Design Megawatt-Sized Circuit Breakers

September 23, 2015
We’ve all stood in the dark at least once after getting tripped up by power-hungry appliances. Typically, the remedy is just steps away: a quick flip of the circuit breaker switch, and you’re back in business.
It’s a simple fix, but it involves complex physics. “Circuit breakers protect our homes from electricity overload,” says Tim Ford, senior product manager for industrial circuit breakers at GE’s Industrial Solutions business. “This sounds easy, but the amount of energy they are often called on to dissipate is like grabbing the flywheel of a running car and stopping it.”

Make this Town an Island: Electric Microgrids Could Shore Up Cities for Future Disasters

September 15, 2015
New York has seen the lights go out in spectacular ways in recent years. Almost the entire state went dark during the Great Northeast Blackout of 2003, and power outages sporadically shut down the 911 emergency services system. In 2008, more than 1.7 million upstate residents were plunged into darkness after a major ice storm split trees and crumbled the grid.

Like Flying 200 Elephants and a Jumbo Jet Full of Oil: What It Takes to Build a New Power Grid in Six Weeks

August 10, 2015
Last December, Egypt decided to move aggressively to avoid power cuts and brownouts during its sweltering desert summer, when the average high temperature hovers above 90 degrees Fahrenheit for months. It had little time to spare. The heat starts rising early in the spring and country’s existing power plants were already operating at peak capacity to support Egypt’s booming economy.

Transformers: Age of Esters. These Engineers Figured Out How to Make Mexico City’s Power Grid Safer

August 06, 2015
When a moderate earthquake shook Mexico City just after midnight in June 2013, an eerie staccato of bright flashes punctured the darkened metropolis. They came from distribution and power transformers exploding around the city. It wasn’t an isolated incident. In December of the same year, another exploding station transformer shut down an NBA game between San Antonio Spurs and Minnesota Timberwolves in the Mexico City Arena.

Europe is Using So Much Solar Power that Today’s Eclipse Could Test its Grid

March 20, 2015
In several ancient cultures, the periodic dimming of the sun during daytime was thought to be the work of giant celestial beasts, who were devouring it. As humanity gained a better understanding of the natural world, people realized that the phenomenon was actually the moon harmlessly passing between the Earth and sun, and blocking light from reaching us. Fear of the solar eclipse turned into curiosity and pleasure.

Gimme Shelter: This Microgrid Could Fight Massive Winter Storms

January 29, 2015
Boston and other parts of the Northeast took it on the chin from Winter Storm Juno on Tuesday. The blizzard was expected to dump up to two feet of snow along the Atlantic coast, stranding people, toppling trees and knocking out power for thousands of residents, including the entire island of Nantucket.But ever since Hurricane Sandy ravaged the area two years ago, engineers and local power authorities have been looking for tools to soften the weather’s blows.

Ships Ahoy: GE’s New Marine Business Leaves Port

January 29, 2015
Last fall, the British Royal Navy commissioned a powerful new high-tech frigate so silent that it would be able to sneak up on submarines undetected. The ship, called the Type 26 frigate, has been designated to become “the workhorse” of the British fleet.
