摘要： In one aspect, the invention provides a method for overcurrent sensing including; generating an analog output signal representative of a sensed AC current, generating a digital representation of the analog output signal using a plurality of discrete samples, determining those of the plurality of discrete samples having a substantially identical magnitude and estimating an amount of overcurrent in the sensed AC current by evaluating those of the plurality of discrete samples that have the substantially identical magnitude. In some embodiments, the substantially identical magnitude is a maximum magnitude represented by the digital representation.

摘要： In one aspect, the invention provides a system for protecting a plurality of circuits including a plurality of circuit protective devices wherein each circuit protective device includes a respective nominal current rating. According to one embodiment, the system includes current sensing circuitry configured to measure a current of each circuit protective device; and a controller configured to receive each of the measured currents. According to one embodiment, the controller is further configured to determine a ratio between a total current being carried by all of the circuit protective devices combined and a total nominal current rating of all of the circuit protective devices combined and employ the ratio to determine a modified nominal current rating of each circuit protective device, respectively. In a further embodiment, the controller is configured to generate an output signal to isolate a selected circuit selected from among the plurality of circuits based on the modified nominal current rating of the circuit protective device included in the selected circuit.
