Abstract: In this paper, an enhanced directional overcurrent relays (DOCRs) coordination scheme is introduced. The proposed scheme considers the fault severity by applying weighting factors, ...

Abstract: This paper describes the application of directional overcurrent protections working in pairs according to the principle of directional comparison in high and medium voltage networks.

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 ...
