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.

A supplemental magnetic trip unit is arranged on the load strap of an industrial-rated circuit breaker to interrupt circuit current upon occurrence of a short circuit fault. The trip unit employs a U-shaped magnet and a hinged armature that articulates the circuit breaker operating mechanism latch to allow the circuit breaker contacts to become separated upon the urgence of the powerful circuit breaker operating mechanism springs.

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, (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, and (c) controlling the first circuit breaker to remain closed until the second circuit breaker is opened.
摘要:
A data sample and transmission module for a power distribution system having a microprocessor, a locator device, and a network interface is provided. The microprocessor samples one or more first signals indicative of a condition of power in the power distribution system. The locator device is changeable between a first state and a second state. The network interface can place the microprocessor in communication with a network so that the microprocessor samples the first signals based in part upon a synchronization signal receivable from the network and so that the locator device changes from the first state to the second state in response to a command receivable from the data network.

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.
