Test the downstream outlet by plugging in the GFCI tester and pressing the test button. Note: The lights on the tester should go out. Fold the wires back into the box and screw on the GFCI receptacle ...

This paper proposes a dc circuit breaker for voltage source converter (VSC) based high-voltage dc transmission (HVDC) systems. Technical challenges for applying dc circuit breakers are to increase ...

This paper presents two high-voltage direct-current circuit breakers that have the capability of interrupting a short-circuit current within several milliseconds. They consist of a current-limit ...
