  • Directional over-current ground relay (DOCGR) using sampled value and method for operating the DOCGR
    Patent number: 11128128
    Abstract: The present disclosure relates to a directional over-current ground relay (DOCGR) for performing a protective relay of the power source system such as a micro-grid system using communications between an SV-remote terminal unit (SV-RTU) and the DOCGR, wherein the SV-RTU is configured for measuring voltage and current of the distributed power source system and thus generating a sampled value (SV) signal. Further, the present disclosure relates to a method for operating the DOCGR.
    Type: Grant
