So you’ve connected a device to your PC via a USB port — but Windows doesn’t recognize it. What now? Before you assume the product (or your PC port) is broken, there are several USB troubleshooting ...

Abstract: Recently many researchers have proposed modifications in objective functions and constraints to improve mathematical formulation of overcurrent relay coordination. Unfortunately, some of ...

Abstract: The reliability and safety of power systems heavily rely on the effective synchronization of relays. Directional overcurrent relays find widespread usage in power systems. The primary ...
