Fundamental overcurrent, distance and differential protection
Overcurrent ProtectionDirectional Overcurrent ProtectionDistance ProtectionPrinciple of Differential ProtectionThis scheme is based on the intuition that, faults typically short circuits, lead to currents much above the load current. We can call them as overcurrents. Over current relaying and fuse protection uses the principle that when the current exceeds a predetermined value, it indicates presence of a fault (short circuit). This protection scheme findsSee more on electrical-engineering-portal IEEE Xplore
