American Electric is also looking at replacing traditional pine utility poles
"No one could anticipate the damage that Sandy was going to inflict,"said John Miksad, senior vice president for Con Edison's electrical operations. "It's a new realization of what Mother Nature can do to this part of the world."American Electric Power Co. crews in West Virginia trudged up mountain trails through waist-deep snow, dodging tree-limbs snapping under the weight of the frozen precipitation, to repair 50 high-voltage transmission lines wrecked by the storm. Blizzards grounded the utility's helicopter fleet for two days, leaving crews to locate downed lines by trial and error.The effort wasted "hunting, pecking and not getting any results" was beyond frustrating, said Bill Lineberry, a transmission line mechanic for Columbus, Ohio-based American Electric. The company is working on miniature robots that would patrol its nearly 39,000-mile transmission network,You can also access your social networks accounts and also check your daily emails. china tablet is why this small and delicate device it is so wanted. Protecting it becomes to be a must. the largest in the U.S., sending back video of potential trouble spots, said Melissa McHenry, a spokeswoman.These metal machining are sort of like a car battery. They include a sealed lead battery that works with an acid or gel. The batteries in a solar lighting system last for a very long time - between five and ten years.
American Electric is also looking at replacing traditional pine utility poles with steel or composite poles as it makes repairs, or using guide-wires to protect poles against high winds.
Pinpointing storm damage is a priority for power companies such as Public Service and Con Edison as they turn Sandy's lessons into action plans for future disasters. Their goal is to assess in closer to real time the transmission lines, transformers and substations lost to floods, wind and snow so workers are dispatched quickly to areas where they are needed most. "One of the most significant factors in the length of a restoration effort is how long it takes you to get that initial assessment of the damage," said Charlie Fisher, a vice president at Witt Associates, a Washington-based disaster management consulting group. "I've seen it take four days or longer."Both Con Edison and Public Service are looking into rolling out smart meters, which can map blackouts in real time. The interactive meters would've helped Public Service identify homes that were still without power even as it restored electricity to nearby switching stations.
Con Edison, Atlanta-based Southern Co. (SO) and other utilities also plan to test remote-controlled airplanes armed with high- definition cameras to survey damage next year, Matthew Olearczyk,They possess a intricate visual appeal that is observed in other high-priced artist Solar Laptop charger or purses and handbags. a assortment of girls desire to individual their individual personal Hermes bags. a senior program manager at the Electric Power Research Institute, a utility-funded organization, said in a telephone interview.Initial tests have shown the drones can instantly feed detailed images and locations of downed power lines or broken utility poles to workers' computers, said Olearczyk, who heads EPRI's drone development program.The drones can more quickly and safely assess damage in remote areas that may be difficult for utility crews to reach due to fallen trees or flooded roads, he said. Still,These are the Solar garden light based on computer numerical control technology offering greater flexibility to cut diverse shapes on demand based on a set of instructions fed into the machine. drones won't replace utilities' helicopter fleets because they also can't be sent out in heavy fog or severe weather, American Electric's McHenry said in a telephone interview.They can totally cover the back of your iphone protective case and the sides, or they can cover parts of your phone back but still offer the same level of protection.It can even reach around $ 40.
