摘要： Described are systems and methods for estimating the resistance-capacitance time constant of an electrical circuit (e.g., of a wordline of a memory device). An example system comprises: a memory device comprising a plurality of memory cells electrically coupled to a plurality of wordlines; a resistance-capacitance (RC) measurement circuit to measure a voltage at a specified wordline of the plurality of wordlines; and a processing device coupled to the memory device. The processing device is configured to: apply an initial voltage to a selected wordline of the plurality of wordlines; discharge the selected wordline for a discharge period of time; float the selected wordline until a voltage at the selected wordline is stabilized; determine, by the RC measurement circuit, a stabilized voltage at the selected wordline; and estimate, based on the stabilized voltage, an RC time constant of the wordline.

摘要： Some embodiments include a system for metering an electrical grid comprising at least one processor executing instructions from a non-transitory computer-readable storage medium of an electrical grid fault detection system. In some embodiments of the system, the instructions cause a processor to calculate a prediction of whether power delivery to at least a portion of the electrical grid is functioning abnormally using voltage sensing devices coupled to at least one feeder, where one or more of the voltage sensing devices are responsive to a determination that the power delivery is functioning abnormally. Further in some embodiments, the determination includes the electrical grid fault detection system receiving at least one signal or voltage reading from the electrical grid based at least in part on a sensed or received voltage level or range of voltage level.

摘要： Systems and methods for coordinating monitoring devices associated with a medium voltage distribution system. The systems include a data aggregation device, a first monitoring device associated with a first phase of the medium voltage distribution system, and a second monitoring device associated with a second phase of the medium voltage distribution system. The first monitoring device is configured to sense one or more parameters of the first phase, store the one or more stored parameters, and determine whether an event has occurred based on the sensed parameters. The first monitoring device is further configured to transmit a coordination signal to a second monitoring device in response to determining the event has occurred and a first event message to a data aggregator device in response to determining the event has occurred, wherein the event message includes one or more sensed parameters associated with the determined event.
