| Abstract: | This paper introduces the operating principle of one intelligent user boundary load switch(IUBLS).By the analysis of short-circuit current about single-phase earth fault,it describes the action principles of IUBLS in detail and proposes the setting calculation principle,implementing scheme and set point of relay protection of IUBLS.The application of IUBLS can effectively curtail the influence of outage caused by facilitate fault and improve power supply reliability significantly. |
