Abstract: This paper presents a novel protection scheme for networked microgrids using Voltage-Accelerated Directional Overcurrent Relays (VADOCRs). The proposed scheme addresses the challenges of ...

Abstract: Lowvoltage DC microgrids represent a highly adaptable approach to bringing renewable power generation closer to consumers, however their large, bidirectional fault currents and quick ...

This 'back-to-the-basics' video that explains how non-directional overcurrent works. It shows the difference between a fuse and an overcurrent protections scheme with current transformer, relay and ...
