High current surges, if unchecked, cause heating of the wires and perhaps melting and consequent short-circuits and fire accidents
Researchers from Indian Institute of Technology (IIT) Kanpur have come up with an innovation that can help protect power grids against sudden, unexpected current surges.
Over a period of about three years, Prof. Banerjee and his PhD scholars have developed this “smart” SFCL device which deploys an array of Hall sensors around a basic SFCL. The array of Hall sensors placed around the SFCL constantly “measure and monitor as well as map” the current flowing inside the superconductor.
