    摘要： A method for locating a ground fault in an electrical power distribution system includes providing a plurality of current sensors at a plurality of locations in the electrical power distribution system. The method further includes detecting a ground fault in the electrical power distribution system. Current is monitored at a plurality of locations in the electrical power distribution system via the current sensors and a test signal is introduced into the electrical power distribution system via a test signal generating device. The plurality of locations are monitored to locate the ground fault between a location at which the test signal is detected and a downstream location at which the test signal is not detected.

    摘要： There is provided a method of controlling circuit breakers in a multi-phase power system. The method includes (a) recognizing a concurrent presence of a first fault in a first phase of the power system and a second fault in a second phase of the power system, where the power system includes a first circuit breaker situated to conduct a fault current between the first and second phases; and (b) controlling a second circuit breaker to open so that the fault current is interrupted, where the second circuit breaker, when closed, provides current to the first circuit breaker.

    摘要： A circuit protection system is provided that provides simultaneous bus differential and transformer differential protection for a power distribution system. The circuit protection system can obviate the need for a circuit breaker disposed between the transformer and the power bus due to the un-delayed tripping of the upstream circuit breaker. The circuit protection system can also provide multiple layers of protection both upstream and downstream of the transformer and the power bus.

    摘要： There is disclosed a protection system for a power distribution system. The system has a processor, a breaker; a network coupled to the processor, a first module coupled to the network and the breaker, a second module coupled to the network, and an algorithm. The algorithm monitors for a permission to trip request. If a plurality of permission to trip requests are received during a given time period, the algorithm issues a permission granted command to the first module and a hold command to the second module.

    摘要： A collapsible contact arm drive link arrangement for a circuit breaker operating mechanism has a pair of upper links for receiving the circuit breaker operating mechanism and a lower link for receiving a circuit breaker contact arm carrier at one end. Intermediate the upper links and the lower link, a scissors link, which is connected with the upper links and lower link, allows the lower link to move from a first position (e.g., closed) to a second position (e.g., tripped). The movement occurs upon the application of a force on the lower link in excess of a predetermined force that is applied to the upper links.
