ABSTRACT:
A circuit testing closer is capable of closing a power distribution circuit and interrupting the resulting current at the next current zero. Upon detecting a fault, the circuit testing closer is operable to open contacts to isolate the fault. Next, the circuit testing closer tests the faulted line to determine whether the fault has cleared. The circuit testing closer may employ one or more dynamic thresholds to determine the existence of a fault.
