Grid “Neurons” Boost Power-Line Performance

Today's typical high-voltage power line, considering its essential role in the electrified world, is surprisingly dull. It's typically just a length of conductor (like aluminum) through which electrons flow from power source to end users. However, researchers have been testing clamp-on sensors to the lines, called power Neurons, that can report fundamentals like operating temperature and current back to grid operators. According to one study by Great River Energy in Minnesota, a pilot deployment of Neurons enabled the utility company to increase its electricity throughput by more than 40 percent. The Neuron's Norwegian creator, Oslo's Heimdall Power, says its sensors are an inexpensive and simple byway to tomorrow's smart grid-coming in at just 2 to 5 percent of the cost of replacing an aging line.
