    摘要: The present disclosure provides a system and method for the management of a monitor module in an electrical measurement system to determine an estimate of a transfer function of a first measurement sensor in the measurement system. The management comprises outputting a first control instruction for instructing the monitor module to determine an estimate of the transfer function of the first measurement sensor over a first individual run length of time, obtaining a first monitor result from the monitor module, the monitor result comprising the estimate of the transfer function of the first measurement sensor and generating a report based at least in part on the first monitor result.

    摘要: A method of detecting a fault in a device is described. The method comprises receiving an energy consumption signal for the device, the energy consumption signal indicating a varying energy consumption of the device over time during operation of the device. A basis function is selected, the basis function defining a signal pattern associated with a known fault type. A correlation between the basis function and the energy consumption signal is evaluated. Presence of an operating fault in the device is determined in dependence on the correlation, and an output is generated based on the determination.

    摘要: An example system includes a failure detection circuit. The failure detection circuit is to detect a failure of a first power source electrically coupled to a first load. The failure detection circuit is to output a first signal indicating the detection of the failure of the first power source. The system also includes a current regulating circuit. The current regulating circuit is electrically coupled to the failure detection circuit. The current regulating circuit is to electrically couple a second power source to the first load based on the first signal output by the failure detection circuit. The current regulating circuit is to restrict a first current from the second power source.

    摘要: An electric power meter capable of monitoring a contact status of a latch relay, comprises: a latch relay having a pair of primary coils and a secondary contact, the secondary contact operable to a closed position or an open position, the primary coils configured to provide a magnetic force to open or close the secondary contact; and a meter controller configured to determine that the latch relay is in a closed position when the input voltage of the primary coils is substantially equal to the output voltage of the secondary contact with a predetermined allowable error range, and configured to determine that the latch relay is in an open position when the output voltage of the secondary contact has not been input, even if the input voltage of the primary coils has been input.

    摘要: The present disclosure relates to generating a measurement sensor profiling summary in relation to a measurement sensor of an electrical measurement system, the measurement sensor being suitable for measuring an electrical property. The profiling summary is generated by obtaining a plurality of profiling results each comprising an estimate of a transfer function of a measurement sensor of the electrical measurement system and a corresponding certainty value indicative of the accuracy of the estimate of the transfer function, wherein the plurality of profiling results are based on estimates of the transfer function of the measurement sensor and corresponding certainty values that were determined by a monitor module of the electrical measurement system during a profiling period of time; and generating a profiling summary based on at least one of the plurality of profiling results.
