Technology Developed by Bar-Ilan University Physicists Earns Additional International Recognition

A technology which eliminates short-circuits and power outages caused by overloaded electric grids, developed by Bar-Ilan University Prof. Yosef Yeshurun and a team of physicists, has been internationally recognized once again – this time by the Science Business Innovation Board, which recently presented its ACES Award in a ceremony held at the ETH science and technology university in Zurich, Switzerland.
The ACES is a pan-European competition among companies spun out from universities to recognize the best academic entrepreneurs from across all technology disciplines. The winners of these prestigious awards were chosen by a distinguished jury of European business and academic leaders, members and guests of the Science Business Innovation Board, a Belgian not-for-profit association created to improve the climate for innovation in Europe.
The Bar-Ilan developed system regulates electrical networks, preventing shorts and other problems, thus stabilizing the electrical grid and protecting refrigerators, washing machines, TV sets, computers, and any other electrical item. It is currently being developed by the Israeli startup company GridOn, which acquired the rights to the technology from the Bar-Ilan Research and Development Company (BIRAD), the technology transfer arm of Bar-Ilan University.
The invention was developed in the National Center of Magnetic Measurements in the Department of Physics at Bar-Ilan University, in cooperation with Ricor Ltd. "The new device is based on a magnetic core which changes magnetic resistance automatically, immediately and passively in accordance with the level of flow in the network," said Prof. Yosef Yeshurun, who led the project. "During normal network activity, the device is not needed and therefore has no influence upon the network, but when there is a short circuit, the magnetic resistance immediately rises and limits increased flow," explain Dr. Shuki Wolfus and Dr. Alex Friedman, who led the laboratory research. This solution, according to Wolfus, is cheaper than any other on the market.
The innovative ideas generated in the Bar-Ilan lab aroused interest at Ricor, a company which specializes in vacuum and deep cooling systems. Together, they embarked upon a joint project partially funded by the Ministry of Industry and Trade. Their prototype was successfully tested in the laboratories of the Israel Electric Corporation. The Bar-Ilan Research and Development Company, headed by Kenan, then assumed responsibility for the commercialization process.
"The constant increase in world energy consumption and production causes a severe and consistent problem of short-circuits and outages in electricity networks around the world," says Prof. Yeshurun. "The Bar-Ilan University invention will enable us to continue to increase production capacity for power transmission networks, while preserving existing infrastructure and improving network stability and reliability."
Late last year, the system developed at Bar-Ilan University was singled out by General Electric as one of five technological developments that contribute most significantly to transforming the electricity network into a greener and smarter one, and which GE has identified as having the greatest potential to change the face of the global electricity market.
