Smart System That Can Protect From Short-Circuits (E)
Researchers from the Indian Institute of Technology Kanpur have developed a prototype of a smart system that can protect power grids from short-circuits. The prototype works by either automatically diverting the current into a parallel shunt or limiting a current surge by developing a high resistance in the current path. Short-circuit conditions often also occur in power distribution networks such as power grids, resulting in huge current surges that can damage the power. In recent years, a new fault current limiter technology has been developed, using superconductors called superconducting fault current limiters (SCFL).An Indian researcher has now developed a unique innovation of a prototype of a Smart Superconducting Fault Current Limiter (SCFLsm), which has a circuit wherein a superconducting element has an array of hall sensors distributed around the superconductor.Developed with the support of DST's Advanced Manufacturing Technologies Program, it is in the fourth stage of the preparation stage, and a national patent has also been filed for it.
