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 circuit protection system is provided that provides a dynamic delay time to an upstream circuit breaker if a fault is detected in a circuit where the dynamic delay time can be based upon the location of the fault, such as the nearest downstream circuit breaker. A control processing unit can determine a dynamic delay time for opening a first circuit breaker if a fault is detected in the circuit. The control processing unit delays opening the first circuit breaker until after the dynamic delay time has elapsed to provide an opportunity for the nearest circuit breaker to clear the fault.

摘要： In order to detect high-speed transients in the alternating current of a power distribution system, the rate at which the power on the distribution system is sampled is increased so that even high-speed transients are detected. The sampling rate can be increased in at least two ways. First, where a single analog-to-digital converter samples multiple lines through a multiplexer, the multiplexer is controlled to allow the converter to sample only one line at a much-increased rate. Alternatively, the sampling speed of the analog-to-digital converter (or A/D array) can be controlled and increased as needed.
