摘要:
A method to protect a circuit having at least a first circuit breaker, and a second circuit breaker arranged upstream of said first circuit breaker, said first circuit breaker having configuration settings selectable between a normal mode and an alternate mode, the alternate mode setting including a reduced energy let-thru (RELT) mode setting having a RELT mode trip time delay. The method including determining if said first circuit breaker is configured in said RELT mode, determining a. dynamic delay time for opening said second circuit breaker, wherein said dynamic delay time is based at least in part on said RELT mode trip time delay of said first circuit breaker, and triggering said second circuit breaker to open after said dynamic delay time has elapsed.

A system for charging a plurality of power storage devices includes a first charging device and at least one other charging device coupled to the first charging device to form a network. The first charging device includes a processor programmed to determine whether said first charging device possesses a network token, and if so, to determine a first charging parameter and a first priority associated with said first charging device, a second charging parameter and a second priority associated with said second charging device, and to determine a second amount of current to be at least one of received from the electrical supply or supplied to the first power storage device, based on the determined first and second charging parameters and first and second priority.

A system for use in supplying current to a plurality of power storage devices includes a first charging device configured to supply current to a first power storage device. At least one other charging device is coupled to the first charging device to form a network and is configured to supply current to at least one other power storage device of the plurality of power storage devices. When the first charging device possesses a network token, it determines a second charging parameter associated with said second charging device, and a second amount of current to be at least one of received from the electrical supply or supplied to the first power storage device, based at least in part on said determined first and second charging parameters.
摘要:
An improved method to detect and locate electrical faults is provided. A method of operating a circuit breaker in an electrical circuit configured with at least one of a first main circuit breaker at a first layer of circuit protection having a first direction of current flow, and at least one second circuit breaker downstream of said at least one first main circuit breaker having a second direction of current flow, and at least one third circuit breaker downstream of said at least one second circuit breaker having a third direction of current flow, wherein one of said at least one first, second, or third circuit breakers is in short time pick-up, is provided, and comprises steps to determine the location of the fault and adjust the trip time delay of the circuit breakers according to predetermined criteria.
摘要:
A revision to a Power Management Control System includes an improved waveform client/waveform server communication interface based on a first inter-process communication protocol, preferably DCOM. The first inter-process communication protocol preferably resides in the waveform application alongside an existing second inter-process communication protocol, i.e. DDE, for backwards compatibility. The improvement allows the application to operate across network segments in a more robust, reliable manner than through the first inter-process communication protocol, thus enabling the waveform server to operate effectively as an NT service and providing independent third party client software access to the waveform server waveform capture functions. The waveform application system comprises interfaces within the waveform server which are implemented by the waveform client, and sink interfaces within the waveform client which are designated for each device class and to which the waveform server fires data as changes occur in the waveform data of the preselected electronic device. A method for communicating between the waveform server and waveform client is also described.
