    摘要: A circuit breaker for protecting a power line. The circuit breaker includes a control unit and a circuit breaking element disconnecting the power line from a power source. The control unit detects a fault on the power line, opens the circuit breaking element, which opening starts a disconnection time interval, injects a test signal into the power line, measures a response, determines an impedance of the power line from the response, analyses the impedance during the time interval based on comparing the impedance with a reference threshold, determines a permanent or a temporary fault based on the analysed impedance, re-closes the circuit breaking element after the time interval if the fault is temporary and keeps the circuit breaking element open after the time interval if the fault is permanent.

    摘要: 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.

    摘要: A circuit testing closer may include a fault isolating switching device coupled between a supply side and a load side of a power distribution system and a current pulse generator coupled in parallel to the switch to generate a current pulse within the power distribution system subsequent to a fault isolation for testing the power distribution system. The current pulse generator may include an electromechanical actuator, an electromagnetic actuator or a solid state switching device. The circuit testing closer may be a purpose-built combination device, or the fault isolating switching device and the current pulse generator may be separately coupled and commonly controlled devices. The fault isolating switching device may have continuous current rating greater than a continuous current rating of the pulse generating device.

    摘要: A fault interrupter and a method of operating a fault interrupter to reduce arcing time during fault interruption. Fault interrupter operation is delayed following detecting a peak current such that its operation occurs at a point of the current wave resulting in reduced arcing during fault isolation.
